OFDM Based Doppler Radar

This project is the code complimenting this thesis:

it requires MATLAB, the MATLAB USRP communications toolbox, and 2 USRPs

Photos of the application running:

To Run [ON LINUX]:

1. Clone repository to local machine

2. open two separate terminal sessions

3. In each start matlab

4. In 1 instance of matlab open runOFDMradarRx.m - This script compiles and runs:

   • runOFDMradarRx.m
   • velocity1B.m

5. In a 2nd instance of matlab open TxofdmRadarTop.m - This script compiles and runs:

   • TxrunOFDMradar.m

6. Connect 2 USRPs to USB ports:

   • ensure USRP platform is configured in TxrunOFDMradar.m & runOFDMradarRx.m ofdmRadarReceiver.Platform='B210'; ofdmRadarTransmitter.Platform = 'B210';

   • make sure serial number is configured in TxrunOFDMradar.m & runOFDMradarRx.m ofdmRadarReceiver.SeralNum='30D0D3E'; ofdmRadarTransmitter.SeralNum = '30D0D28';

   • make sure you are transmitting/receiving on expected port / antennas are wired correctly.

   • Set ChannelMapping appropriately in runOFDMradarRx & TxrunOFDMradar: 'ChannelMapping', 1, ...

7. Hit run on each matlab session (each will take a while to compile an begin upwards of 45s - 1 minute)

8. runOFDMradarRx.m should display a plot once it starts receiving transmitted OFDM symbols
