Blind Channel Estimation for OFDM Systems Based on Non-redundant Precoding
摘要
Abstract
The channel estimation is one of the key factors for wireless communication transmission. The existing blind channel estimation algorithms have such disadvantages as high computation complexity and low accuracy for OFDM communication system. In this paper,we propose an improved non-redundant precoding assisted blind channel estimation scheme for SISO-OFDM system. In the proposed scheme,the principal eigenvector is obtained by the power method with low complexity instead of the complicated eigenvalue decomposition. Simulation results show that the channel estimation and bit error rate performance of the proposed scheme is superior to that of the conventional precoding assisted blind channel estimation scheme,and gains a better estimation effects.关键词
