Abstract

The demand of Orthogonal Frequency Division Multiplexing (OFDM) has been increased from last few decades in wireless communication system. Channel estimation is the essential problem in OFDM system. Channel response can be obtained by employing pilot in payload symbols. In this paper we are estimating channel in OFDM system using pseudo-pilot inplace of pilot symbol. We are showing that the performance of proposed method is AWGN fading channel is better then the performance of pseudo-pilot in Rayleigh channel. In OFDM technique we are using time domain so signal in the series so we cannot used more signal it can use proposed channel estimation to estimate the channel impulse response using pseudo-pilot. The modulation technique used is QAM.
