Paper Title - Maximum a Posteriori Based Iterative Channel Estimation for OFDM Systems


Abstract
This paper investigate the Iterative Channel Estimation for Orthogonal Frequency Division Multiplexing over wireless channels. Iteration Channel Estimation utilizes data symbol estimates to improve the channel estimation performance. Maximum A Posteriori approach provides the optimum Iterative Channel Estimation for the OFDM system. The Maximum A Posteriori based Iterative Channel Estimation performs well over threshold controlled based Iterative Channel Estimation at low and mid range of SNR. The Maximum A Posteriori based Iterative Channel Estimation has converged within one iteration for a high SNR. If SNR is low, this approach yields a little performance improvement for next iterations. Index Terms - OFDM, iterative channel estimation, EM algorithm, performance bound.
