BER Simulation and Comparison of OFDM Signal under AWGN and Rayleigh Fading Channel

A. S. Bahuguna; Dr. Sanjeev Naithani; Sunil Semwal
In this paper, we investigate the bit error rate (BER) performance of orthogonal frequency division multiplexed signal and its comparison under AWGN and Rayleigh Fading Channel. As we know that OFDM is a special case that can be seen as either a modulation technique or a multiplexing technique. Orthogonal Frequency Division Multiplexing is modeled and simulated under different channel conditions such as AWGN and Rayleigh fading. Subsequently, a comparison study is carried out to obtain the BER performance for OFDM under one-path fading channel and AWGN channel condition to identify that which channel gives the best BER performance. The comparison study showed that BER for AWGN channel gives the best BER performance compared to Rayleigh channel.
