MATLAB program for OFDM generation and reception



This is a simple MCM communications system. The code is pretty self-explanatory. Here I have not used the cyclic prefix.



Transmitter End:

1. Generate random serial data with M symbols (RANDSRC will do this)

2. Perform modulation (4-PSK = QPSK for now)

3. Serial to parallel

4. IFFT

5. Parallel to serial



Receiver end



Just opposite of transmitter end.
