Abstract

Randomness of wireless channel, in order to accurately recover the transmitter signal, requires to estimate the channel. This paper has been introduced some channel estimation algorithms which are based on the pilot frequency. It respectively analyzes and compares performances of the Least Square error (LS) and Minimum Mean Square Error (MMSE) and Linear Minimum Mean Square Error (LMMSE) algorithm in MIMO-OFDM wireless communication system. At the same time, it analyzes the performance of the three algorithms by increasing the multipath path. Experimental results show that, when the receiving signal under the condition of high SNR, considering the performance and computational complexity comprehensively in the channel estimation algorithm, the LS algorithm still has a very good application prospect.
