This paper makes theoretical analysis on the divergence of the transmission alignment of the MRT, presents the method of attenuation of memory to control the filtering divergence of the transfer alignment. By the mathematical simulation, we find the method of attenuation of memory can effectively restrain the filtering divergence of the transfer alignment, ensuring the accuracy of the filtering accuracy of transfer alignment.
