In this paper, a novel ADSL channel equalization method based on evolutionary algorithm is proposed, in which we establish the equalizer through the method of channel identification.The proposed method is capable of simultaneously evolving both coefficients and the ranks of the equalizer and therefore it can be applied to different characteristics of loops. Experimental results show our method has better performance (short search time and high modeling precision).展开更多
