Equalization in WIMAX System

This paper theoretically explains and demonstrates the MMSE and ZF equalization in WIMAX system for Rayleigh channel model. The ZF equalization performance depends on the ........ value of the equalization factor, which are varied from -0.1 to 0.1, reflecting the difference in BER value of the WIMAX system. The techniques used for the channel equalization mitigate the effect of ISI with an improvement in BER value compared to the existing technique. The focus of this paper is to corresponding generation of the reference sub- carriers and reducing the channel effect at the receiver by the inverse approximation filter and by the minimization of error signal. The graphs are represented by the computer simulations in this contribution are genuine.
