LS estimation algorithm does not need to understand the statistical properties of channels,which require relatively simple structure of the receiver,in the actual application of the system,has certain advantages,but the noise of the existence of such a channel estimation of the performance and the ideal channel differences,the system greater impact on performance.This study analyzed the least squares(Least Square LS) channel estimation algorithm based on the algorithm to improve and reduce the noise on the channel estimation.The simulation results show that the algorithm to reduce the channel is estimated that the mean square error,the LS is estimated to increase the accuracy of the algorithm.
