radfordneal / ldpc-codes Goto Github PK

sir i am trying to run LDPC-codes in Ubuntu 16.04 but i don't know how to run it.i tried to check any redme file for instruction but i didn't get anything.please guide me.

Hello @radfordneal,

For context, the package of openfec has just been rejected from Debian because it contains some LDPC codes with the following license:

 Permission is granted for anyone to copy, use, modify, or distribute these
 programs and accompanying documents for any purpose, provided this copyright
 notice is retained and prominently displayed, along with a note saying
 that the original programs are available from Radford Neal's web page, and
 note is made of any changes made to these programs.  These programs and
 documents are distributed without any warranty, express or implied.  As the
 programs were written for research purposes only, they have not been tested
 to the degree that would be advisable in any important application.  All use
 of these programs is entirely at the user's own risk.

The questionable part is ... this copyright notice is retained and prominently displayed, ... because we don't know if Debian fulfills this requirement knowing the license and copyright are in the header of relevant files, moreover we provide a summary of all licenses of a software in a debian/copyright file as you can see for openfec here.

If would be wonderful if you could confirm it is enough to be compatible with prominently displayed.

Thank you!

Best regards,
Dylan

i have done creating a parity matrix ,encoding message and transmission and i unable to do decoding.
i am using below command to do decode.
decode -f -T p.pchk pencode1.txt pdecode.txt bsc enum-block p.gen

but it showing error
Usage:
decode [ -f ] [ -t | -T ] pchk-file received-file decoded-file [ bp-file ] channel method
Channel: bsc error-probability | awgn standard-deviation | awln width
Method: enum-block gen-file | enum-bit gen-file | prprp [-]max-iterations

where
p.pchk -> pchk-file e
pencod1.txt ->received-file
pdecode.txt-> decoded-file
bsc -> channel
enum-block -> method and p.gen is generation file.

sir, i read the given documentation and run the example it is working fine.if i want to send message to anyone what can i do?
