Abstract

Abstract: Based on the sparse-leakage channel, a novel channel parameter estimation method is proposed. This method exploits the correlation of the paths of the discrete-time correlated multipath channel to estimate the delay and amplitude of the original channel. Since the number of paths of the original channel is much smaller than that of the discrete-time correlated multipath channel, proposed channel parameter estimation method can suppress the AWGN and improve the accuracy of the channel estimation.

Key words: OFDM, multipath fading channel, channel estimation
