Wireless Communication is one of the most rapidly growing industries. The high demand for wireless communication services had led to an increase in system capacity. Then most elementary solution would be to increase bandwidth however, this becomes ev

the effects of neural network aided estimation in such receivers are considered. Neural network acts as a pre-processing block to the estimator.-Orthogonal frequency division multiplexing (OFDM) has high data rate capacity and lower Inter Symbo
