摘要：In this paper,We propose animproving algorithm ofthe EM about the OFDM system under the condition offast-moving for channel estimation improvement algorithm. This algorithm is greatly reduced computational complexity compared with the original algorithm and makes the SNR performance close than without jamming. On the development of mobile communications has a good theoretical significance.
