  • Based on the property of OFDM systems, this paper discusses the feasibility of Wiener LMS algorithm in OFDM systems, and derives the frequency expression of the WLMS channel prediction algorithm for OFDM systems. The performance of the algorithm is greatly improved by using a frequency domain filter, which is derived based on the correlations of channel response in frequency domain, in each iteration. The simulation results show that the performance of uncoded Symbol Error Rate (SER) can reach the bound of ideal channel estimation at the proper step size.
