Orthogonal frequency Division Multiplexing (OFDM) is a multicarrier modulation technique where high rate data stream is divided into a number of lower rate data streams and transmitted over a number of subcarriers. Quadrature Phase Shift Keying (QPSK) & MPSK (M-ary phase shift keying) can be combined with OFDM for better data transmission taking the advantage of both OFDM & the different high rate modulation techniques. This paper discussed M-PSK- OFDM system where the information bits are already modulated using QPSK and M-PSK process. A comparative study of bit error rate (BER) vs. SNR under normal AWGN & multipath fading channel has been done between different M-PSK OFDM techniques using MATLAB Simulink model.
