发射分集OFDM系统中的一种维纳LMS信道估计和跟踪算法
摘要
针对发射分集的OFDM(orthogonal frequency divided multiplexing)系统
A Wiener LMS channel estimating and tracking algorithm for OFDM systems with transmitter diversity was proposed. The algorithm used Wiener prediction technology to improve the ability of tracking channel. The simulation results show that the algorithm achieve reliable channel estimation. The performance is improved greatly compared with conventional algorithm LMS algorithm and simplified algorithm proposed by LIYe and this improvement is obvious under fast varying channel.
