In this paper, the authors investigate the Bit Error Rate (BER) performance of Orthogonal Frequency Division Multiplexing (OFDM)-Binary Phase Shift Keying (BPSK) OFDM-Quadrature Phase Sshift Keying (QPSK), OFDM-Quadrature Amplitude shift keying (QAM) over different fading channels. The performance of transmission modes are evaluated by calculating the BER versus Signal to Noise Ratio (SNR) under the Additive White Gaussian Noise(AWGN), Rayleigh fading, Rician fading, Nakagami-m fading channel. In particular, the simulation of OFDM signals with different modulation schemes over different fading channels is carried out. Their simulation results are enough to understand the effect of fading channels with different modulation schemes and to verify the best suited fading channel in terms of BER Performance.
