摘要 对MIMO-OFDM系统的多种信道估计算法进行了探讨,重点对基于导频的信道估计算法LS、MMSE以及ZP-OFDM的盲信道估计算法进行了分析和比较,并对LS、MMSE以及ZP-OFDM的盲信道估计算法分别进行了仿真实验,仿真结果表明了算法的有效性,对盲信道估计算法的研究有很好的参考价值. This paper focuses on the channel estimation algorithms for MIMO-OFDM Systems.Both of LS channel esti-mation algorithm and MMSE algorithm are based on pilot.MMSE algorithm has better estimating performance than LS algorithm.ZP-OFDM blind channel estimation algorithms is applied to blind channel estimating,the simulation results show the effectiveness of algorithm,the relationship between MSE of channel estimating and different length of data is given.
