Description: 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.
