| Abstract: | The application background of reducing the multipath effect and promoting the efficiency of sig- nal transmission. The principle of decision-feedback equalizer algorithm（DFE） based on the algorithm of CMA is introduced,and a new algorithm of fractionally spaced variable step decision-feedback equalization algorithm is proposed. The capahility of this algorithm is simulated and analyzed. The result of the experiments shows that the new algorithm gets significant improvement in convergence speed and residual error and has a actual value. |
