Abstract

The MMSE linear equalization algorithm in SC-FDE system is analyzed in this paper.An algorithm to evaluate the energy of white noises and to improve the equalization algorithm in SC-FDE system is proposed.The simulation results under the Matlab show that the experimental value of BER with the improved algorithm is well matched with the theoretical calculation value,and the constellation convergence is well done.Thus the performance of the communication system is greatly improved.
