A Novel Channel Equalisation Technique for Mimo-Ofdm System

In any communication system, the emphasis is on estimating the channel response so as to retrieve the transmitted input signal accurately at the receiver's end. Channel Equalisation at the transmitter refers to pre-distorting the input signal so that the effect of the channel is nullified during transmission.By evaluating the inverse of the filter F and passing the symbols through a filter designed with frequency response F-1, we can equalise the distortions on the input due to channel. The proposed method shows a better Bit Error Rate (BER) performance than that of the usual way of channel equalization in the respective systems.
