This example is based on IEEE 802.11a OFDM protocol.

Using Software Designed Radio (SDR) to transmit OFDM signals at 5 GHz.

Transmitter and Receiver hardware : Zedboard (Xilinx Zynq®-7000) + AD9361 (Analog Device-FMCOMMS3)

Before executing this code, please follow this tutorial to install support package for Xilinx Zynq-Based Radio in Matlab.

Please open multiple Matlab windows to run Hardware_TX.m and Hardware_RX.m respectively.

Edit newip.sh file in SD card

# Flush existing config
ip addr flush dev eth0
ip link set dev eth0 down
# Set up new config
ip addr add 192.168.3.3/24 dev eth0
ip link set eth0 address 00:0A:35:00:01:23
ip route add default via 192.168.3.1
ip link set dev eth0 up

Then, use router DHCP hand setting mode to distribute network configuration parameters :

• "Delay and Correlate" algorithm for Packet Detection

• Packet Detection (normal case) , Threshold=0.75

• Packet Detection (problem case & deselect the imperfect packet)

• Coarse CFO Estimation & Compensation

• Fine CFO Estimation & Compensation

• Channel Estimation & Equalizer
