Description: 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.
