Abstract
This paper presents a novel method for OFDM demodulation based on LMS adaptive filter. In this proposed method, data symbol is reconstructed from amplitude of reference signal without using fast Fourier transform and thus this method can be applied for real time system. In addition, the convergence rate of adaptive filter can be promoted by using the proper initial weights. The proposed technique will be applied for BASK-OFDM, BPSK-OFDM and QAM-OFDM demodulation. The obtained simulation results of the proposed method compared to the conventional scheme show that the proposed technique can be applied for real time processing of OFDM demodulation.
