Abstract

Abstract: 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.
