Abstract :
In this paper, in order to improve the Bit Error Rate (BER) of digital communication OFDM in a multipath channel, we combine the algorithm Maximal-Ratio Combining (MRC) diversity with orthogonal frequency division multiplexing (OFDM) system, the main idea of using MRC diversity is to improve the signal received at the receiver. One of the many methods which can be used to reduce the impacts multipath due to mobile radio channel is to employ an adaptive equalization. Simulation results are given and discussed.
