Abstract

In the communication system, the error rate of signal transmission in the channel is high. The use of OFDM (Orthogonal Frequency Division Multiplexing) technology can reduce the bit error rate and improve the quality of signal transmission. Channel estimation algorithm, as a key technology in OFDM system, is particularly important. In this paper, three common channel estimation algorithms are analyzed, and the pilot channel estimation methods are emphatically studied. Their advantages and disadvantages are analyzed, and the future development prospects of this technology are prospected.
