摘要 本文讨论在MIMO-OFDM系统中实现信道估计的算法仿真。文章从导频序列的选择开始,研究了在瑞利信道下的LS估计算法、分离的一维维纳滤波算法以及利用SVD奇异值分解简化的维纳算法。并通过分析仿真结果得出各种方法的性能比较。 This article present the simulation of channel estimation methods in the MIMO - OFDM systems. Beginning from how to choose the optimal pilots, the article discusses the LS estimation method, separated one - dimension wiener filter method and the SVD predigested wiener method based the Rayleigh channel. Through analyzing the result of simulating, the article gave the comparing of the estimation methods performance.
