Executive Summary

Multipath fading is the major problem facing any wireless communications system. Orthogonal Frequency Division Multiplexing (OFDM) is considered efficient solution for mitigating fading distortion especially frequency selective type. LTE and WiMAX families are based on OFDM technology which is the main reason for those systems high efficiency. In this paper two techniques will be joined in order to mitigate distortion caused by multipath frequency selective fading channel. Channel estimation and equalization are necessary processes when the channel is time variant, as usual for most wireless channels. System performance has been analyzed based on BER level obtained at the receiving end versus variation in SNR at different system situations.
