Abstract

OFDM is being widely used in many communication systems for its ability to enhance the data rate and reduce the bandwidth. The paper gives a comparison of the performance of OFDM system using different modulation schemes under the influence of AWGN and Rayleigh fading channel. Simulations of OFDM signals are carried out with Rayleigh faded signals to understand the effect of channel fading and to obtain optimum value of Bit Error Rate (BER).

Keywords
