OFDM Signal generation and decoding using QPSK as the modulation
technique. This type of OFDM is particularly useful for WiMAX and other
Wireless and Multimedia Standards. QAM4 and QPSK is same modulation
technique. Just run the Model and with different SNRs in the Channel
Block observe the performance of the OFDM. Please leave your feedback
for the model so that we can improve it. <br>
