摘　　要：信道估计技术作为获得信道信息的手段,是提高无线数据传输接收性能的关键技术之一。本文分别在不同的条件下对LS(Least Square)、LMMSE(Linear Minimum Mean Square Error)、SVD(Singular Value Decomposition)三种信道估计算法进行仿真,对比分析三种算法的MSE(Mean Square Error)和BER(Bit Error Rate),并得出相应的结论。Channel estimation technology as a means of access to the channel state information is one of the key technologies to improve the reception performance of wireless data transmission. In this paper, three kinds of channel estimation algorithms which are LS （Least Square）, LMMSE （Linear Minimum Mean Square Error）, SVD （Singular Value Decomposition）, are respectively simulated in different conditions. The MSE （Mean Square Error） and BER （Bit Error Rate）of the three kinds of algorithms are analyzed and compared, then the corresponding results are concluded.
