szechyjs / dsd Goto Github PK

This is relevant since cmake isn't necessarily installed by default.

It might be worth adding that mbelib and dsd can be built in Cygwin (preferably Cygwin32 as I've run into several annoying bugs in some packages).

Hi.
I would like to see a feature of the MotoTRBO GPS Not to tell me where abouts but to say on DSD that GPS is been used.

Francis.

In the file dsd.h, I can find the sync
#define NXDN_MS_DATA_SYNC "313133113131111333"
#define INV_NXDN_MS_DATA_SYNC "131311331313333111"
#define NXDN_MS_VOICE_SYNC "313133113131113133"
#define INV_NXDN_MS_VOICE_SYNC "131311331313331311"
#define INV_NXDN_BS_DATA_SYNC "131311331313333131"
#define NXDN_BS_DATA_SYNC "313133113131111313"
#define INV_NXDN_BS_VOICE_SYNC "131311331313331331"
#define NXDN_BS_VOICE_SYNC "313133113131113113"
But in the file NXDN Technical Specification Part 1 Airface chapter 4.4.4 Frame Sync Word, I can find only 0xCDF59(SYNC). The sync in protocol is shorter than the one in the header file.
Is there anyone can tell me in which file , I can find the complete sync of NXDN. Thank you!

Prior to 12-16-2013, DSD had a Makefile. None exists now, and thus it is not possible to issue a 'make' to build DSD.

Hi,

First off, thanks very much for this great utility. Just FYI, I've been able to get voice stats off P25 using this in conjunction with rtl_fm:

rtl_fm -f XXXXX -p 49 -s 48000 -g 25 -M fm | dsd -i - -o /dev/null -v99 -g25

(Please let me know if you have any suggestions re: these options, but right now they seem to work well).

I'm hoping to get more info from the P25 control channel, and unfortunately my C++/SDR skills are pretty much nonexistent. Any way this could be placed on the roadmap, or have I overlooked this functionality?

I'm getting this when trying to run make after cmake.

It's on a system running Mint 18.1 64 bit.

It seems that DSD crash when there is two audio slots active at the same time. (mototrbo)
it Sometimes keep on working but only decode one slot from then onwards.
It seems to switch to a slot and disable the other slot until restart.
(Maybe its a mono / stereo ALSA problem ?)(What format is the stream to ALSA?)
Maybe sending slot0 to Left and slot1 to Right audio channel mite fix the problem. (stereo)

I have no clue what can be done to solve this. Thanks a lot in advance for any help.

Fred

Each of the different voice formats has a different text output format. These have probably evolved over time and were largely meant for eyeball consumption. A uniform format for script parsing would be nice to have. Perhaps JSON objects listing the type of sync and sub-elements based on the type, eg: talkgroup and source IDs for P25, DMR; callsigns for D-STAR, etc.

Hi, after installing dsd-master, mbelib, libsndfile, it++ on ubuntu 14.04, itried to run dsd but this error occur:
error while loading shared libraries: libmbe.so.1: cannot open shared object file : no such file or directory.
Please help!

I would like somebody to possibly implement an encryption mode for basic privacy usage only from 1 - 255 to dsd1.70. I am not a programmer but surely someone out there is and capable of doing a little work on the side. Not forgetting that BP is a moto proprietary product

I suggest to add the key word "const" to the type specifiers for parameters like the following.

• opts, imbe_d (function "saveImbe4400Data")
• parity (function "decode")

Would you like to apply the advices from an article to more places in your source files?

Hello,

I am running dsd with the -d parameter like this:

dsd -i /dev/dsp -o /dev/dsp -fd -d /home/user/dsd-rec/

but the files are stored in the directory /home/user/ from where I start DSD.

It would be nice to have ALSA support for audio in and out?

Hi,

Are you going to make support for Yaesu Fusion? It look's that voice codec is the same so maybe to will be not so big problem.

Best regards

Piotr

Hello,

I have practical problem where I have two DPMR stations, which are claimed to follow DPMR standard, but which do not work with each other. Problem seems to be not only with the voice codec, but also with the protocol itself as even messaging does not work.

DSD open source version does not have support for DPMR, only DSDPlus has, but DSDPlus does not have an option for more deeper stream analysis. It only detects when data or voice frame is received, it is able to detect data/voice frames on the data, which I'm supplying.

Is there any chance to add support for DPMR or are there any guidelines on what kind of modifications to demodulator should be done to get valid bit stream. Tried to play with current demodulators in DSD, but could not find valid DPMR frame sync which is given by DPMR specification: https://www.etsi.org/deliver/etsi_tr/102800_102899/102884/01.01.01_60/tr_102884v010101p.pdf DPMR is using 4FSK, but seems that there is no demodulator in DSD, which is capable to deal with it.

It would be really nice if DSD will have support for DPMR and DPMR stream dump for deeper analysis (for example, to Wireshark compatible format), it will allow to find classes of these cheap DPMR stations which are interoperable.

Thank you.

I noticed decoding of NXDN96 was poor with the upstream code I pulled. I noticed in dsd_symbol.c that the NXDN48 filter is used for both NXDN48 and NXDN96. I fixed the poor decode problem in my repository by using the DMR filter for NXDN96 as they have the same filtering requirements.

Hi all,

I'm looking through dsd_frame.c, and at https://github.com/szechyjs/dsd/blob/master/dsd_frame.c#L270-280 is where the 4-bit DUID is extracted. However, I notice that even though 2 dibits are read, only the most significant bits of each are used (and subsequently compared). Is this intentional?

The reason I ask is because the trunking protocol uses a DUID of 0x7 or 0xC which can't be represented by 2 bits.

My guess is newer chipsets can't go down to 8000 natively. Will probably have to look up the native resolution of the device and upsample in the wrapper.

I noticed that FECdecoder appears to implement a trellis decoder. Will this work with the P25 control channel (assuming you initialize it the same way as in dstar_header_decode)?

I would like to point out that identifiers like "__HAMMING_HPP__" and "__P25P1_HDU_H__" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

To assist with the unit testing of dsd input files will be necessary. It would be nice to come up with a collection of various types of raw input files that can be used for testing purposes.

Using cmake version 3.0.2 (mkdir build; cd build ; cmake ../)
I get a warning that test/CMakeLists.txt line 15 is using the target name "test" which is now reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior.
This warning is for project developers. Use -Wno-dev to suppress it.

I can use cmake -Wno-dev ../ and ignore it, but I thought I'd let you know.

Is it possible to decode the direct mode data transmission or MS inbound frequency data transmission?

Is the Unit ID / Source ID covered by any error correction or detection? I am getting some really weird values for Source. I have been logging them, and I am getting a bunch of Source IDs that are high and only show up in a single LCW message.

Is there another P25 Message that also contains Source ID and is covered by error correction or detection?

I have compiled the dsd on Ubuntu 14.04LTS for purpose of extracting data from DMR data packets.
The only data I get out of it is on stdout info output.
I am running dsd in following way:
padsp -- dsd -i /dev/dsp -o /dev/dsp -v99 -n -fr -mc
while gqrx is tuned to the station.
This gives me this output:
....

...

I looked through help menu and there it seems that there is no way to extract data or redirect data packet content.

Is this even possible with DSD?
My C knowledge is very rusty, but if someone would point where to look in the source, I would be very happy.

This is a very similar request: #37

Thanks a lot!

Sergei.

P.S. I occasionally get segfaults, like so:
segfault at 7f5b88ffd000 ip 0000000000413252 sp 00007fff4ece1a40 error 7 in dsd[400000+2e000]

It would be nice to have an audio input and output level indicator.

I am not able to compile DSD on OS X with the latest version of XCode (5).

Feature, wishlist.

Allow reading audio from a UDP socket instead of the soundcard. This would allow for easier integration with gqrx: http://gqrx.dk/doc/streaming-audio-over-udp

Currently working with:
socat udp-listen:7355 - | padsp ./dsd -i /dev/stdin -o /dev/dsp

Do you think it would be possible to include displaying NXDN metadata (especially User ID)?

Tried to run DSD on Raspberry.

+DMR messages are printed out to console, seems to be able to decode.

But when audio is recorded to .wav file it is chopped, not possible to understand a single word.

Tried to use mbuffer thinking that pipe is not large enough to hold all the data when dsd is not able to consume fast enough, but it still the same.

Is ARM architecture supported by DSD/MBElib or is Raspberry not powerful enough to run it?

Anyone tried to use DSD successfully on Raspberry or other ARM device?

I have a P25 encoded audo sample in ogg format.

I wish to pipe this to DSD via stdin with the following command:

ogg123 -d raw -f - ~/Downloads/P25Audio.ogg | ./dsd -i - -o pa:1

However this appears to run the first command (which has an incrementing status bar, as below) THEN runs DSD which gives an output as if there wasn't anything to decode:

Time: 00:02.72 [00:20.69] of 00:23.41 (105.6 kbps) Output Buffer 77.8%

Is there a simpler way to achieve this? My reason for asking is that I have GQRX successfully streaming via UDP to DSD, but haven't managed to get a any useful audio out of DSD, possibly because I'm not getting a strong enough digital radio signal within GQRX (Which is a separate issue). I wish to pipe the sample ogg file to DSD to confirm this part is working, with GQRX out of the equation.

The command's full output is below:

ogg123 -d raw -f - ~/Downloads/P25Audio.ogg | ./dsd -i - -o pa:1

Unless your running linux that is not cutting edge then getting audio input/output to work with dsd can be troublesome. I'd like to use PortAudio for this as it provides compatibility with Windows, Mac, and Unix systems.

Hi there. This is just a question, not a bug. I'm playing with the p25_raw_unencrypted.flac from the samples repository. Towards the end of the decoding there is an LDU with many errors:

Sync: +P25p1 mod: QPSK inlvl: 20% nac: 1F5 src: 4270002 tg: 7455 LDU1 e:==========R==========R==========R==========RM==========R==========R

I've been debugging this. Seems like in this LDU the IMBE words from 4 to 9 are all exactly the same, with a C0 which looks like:

data: (0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0)
golay23 parity: (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)

The parity is not correct for that data, hence the decoding errors. But I don't think it's an error. Since this is repeated exactly on 6 IMBE words I believe it's intentional. The BER for this sample is fairly low.

There are some special values for IMBE words to encode silence or tones, but they should come with a valid golay23 parity. This one doesn't.

If this is a special case, I cannot find it in the P25 documentation or anywhere else. Might this be specific to the radio device used? Some kind of non-standard value that got some meaning for the vendor? It's a the very end of the speech.

From Boatanchor on RR:

The recovered P25 audio does seem a little 'narrow' compared to DSDPlus. DSD has a bandwidth of 0-3500Hz, whereas DSDPlus extends the high frequencies up to >4Khz. Many people say they prefer the DSDPlus audio (I'm not necessarily one of them, but it would be nice to be able to adjust the top end roll off / LPF point)

The output audio is constrained to the bandwidth that a short (32,768Hz) can support, we should probably use sf_write_float rather than clipping values to a short.

Hi jared,

love your dsd its works great,
i'm a student, and i want to know more about the samples in .raw and .rawiq files,
i want to open them in matlab and see the signals, i know that the file data look like this 48k/16bits/mono/pcm, but how one sample of 16bit looks like? and what it presents?

Thank you.

Im decoding a p25 tunked system using unitrunker and DSD. Sometimes the decoded audio from DSD sounds very choppy. And happens a lot with different p25 signals whether it be trunked or not. I don't know if its an error in the decode or something but I do get little errors and sometimes the R and M symbols but I can't tell why since the signal is pretty strong.

EDIT I just found out when the audio is choppy it sometimes says Non-standard IMBE c0 detected, skipped. Or it also sometimes says Ignoring LDU2 not preceeded by LDU1.

Does that mean the signal is bad? When I listen to my own recorded raw audio the actual raw audio sounds pretty strong and barley any static or signal drops.

As referenced in the following closed pull request DSD apparently needs to be modified to work on OS X.

#1

See also the FAQ section at the bottom of:
http://wiki.radioreference.com/index.php/Digital_Speech_Decoder_(software_package)

I am re-opening this as a separate issue since the cmake change that was the subject of the previously mentioned pull request was merged in and closed without addressing the /dev/audio issue.

I have a homebrew formula pull request ready to go which compiles and installs both DSD and mbelib with a one line 'brew install dsd' on OS X. I am reluctant to submit this pull request until I can test DSD locally with a sample file (e.g. a mototrbo capture from the discriminator tap of a scanner). The pull request for mbelib formula has already been submitted:

Homebrew/legacy-homebrew#21792

I'd love to see this working on OS X so I can capture signals using OS X SDR software or a scanner with a discriminator tap and feed them to DSD for realtime playback.

Hi - I am getting a segmentation fault from the new heuristics error correction. I have incorporated DSD into a gnuradio block and I am running several instance in parallel, so it could easily be that. However, I think there might be an error in the DSD code.

In p25p1_tdulc.c, on line 291 read_zeros gets called with new sequence set to zero.

As a result, sequence_broken for the first element of analog_signal_array is 0 on line 194.

Next contribute_heuristics is called. That brings us to line 186 of p25p1_heuristics.c.

prev_dibit = analog_signal_array[i-1].corrected_dibit;

This is in a for loop that sets i from 0 to 10. I am getting the segmentation fault when i=0 because a crazy value is pull from analog_signal_array is pulling a crazy value out and setting prev_dbit to it. This then gets passed to update_p25_heuristics and prev_dbit is used to pull the symbol heuristics:

sh = &(heuristics->symbols[previous_dibit][dibit]);

In short, it seems like in p25p1_tdulc.c, on line 291 new sequence should be set to 1. I made the switch and it seems to prevent the seg fault.

Also in p25p1_tdu.c on line 21, read_zeros is called with new sequence set to 1.

Hi everybody,

The specifications (TS 102 361-1) (see page 60/177) describe the CACH structure as follow:

AT: (IDLE / BUSY)
TC: (CH1 / CH2)
LCSS: (Single, First, Last, Continuation)

Well, now this is how processDMRdata() read the TC bit:

I really don't understand how we can get the "TC" bit like that, in my opinion we are taking the left bit of the byte[2] so we are in "LCSS". (bit 4)

Any ideas ?
Thanks
