Performance of channel estimation and equalization in OFDM system

Orthogonal Frequency Division Multiplexing (OFDM) [1] [2] has recently become the most attractive modulation scheme in wireless communication system. In this paper, Orthogonal Frequency Division Multiplexing (OFDM) is analyzed and simulated with channel estimation and equalization under Rayleigh fading channel. The performance is evaluated in terms of bit error probability. The channel estimation increases the equality of OFDM system by improving the system performance in terms of bit error rate. From the simulation results, it is demonstrated that Weiner filter provides better estimation and OFDM performance is better under Rayleigh fading channel, than Rician fading channel.
