SDR_Matlab_LTE

This simple OFDM demo is based on LTE downlink format for testing SDR hardware.

Using Software Designed Radio (SDR) to transmit OFDM signals at 2.4 GHz.

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

Software needed :

• Matlab (R2018a version in this example)
• Libiio Library
• Zynq Linux Image (2015_R2-2016_07_26 version in this example)

Code Structure :

Please open Matlab windows to run

• Main_self.m for one transceiver
• Main_TwoBoard.m for transmitter and receiver

The way to change Hardware IP / Mac address

Edit /etc/init.d/rc.local file in Linux OS

## Change MAC address
sudo ifconfig eth0 down
sudo ifconfig eth0 hw ether 00:0A:35:00:01:23
sudo ifconfig eth0 up

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