Tone Modulation

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...

OFDM Signal generation and decoding using 64-QAM as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. Just run the Model and with different SNRs in the AWGN Channel Block observe the performance of the OFDM. Please leave your...

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment.It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER.I hope this will help students alot.Please feel free to contact me should anyone has any queries.
