摘要
提出了一种基于分数采样的变步长LMS算法,该算法利用分数采样使之含有更多的信道信息,从而得到更小的稳态误差,利用变步长来加快算法的收敛速度。与常规LMS算法,基于分数间隔的LMS算法相比,新算法具有更快的收敛速度和更小的稳态误差。电话信道的仿真结果,验证了算法的有效性。
A novel Variable Step-Size LMS Algorithm Based on Fractional Sample Equalization is proposed, via full using fractional sample to have a smaller MSE, and variable step-size to have faster convergence rate, which made it concluded more channel information. Comparing with normal LMS and LMS algorithm based on fractional sample, the new algorithm has faster convergence and smaller MSE. The efficiency of the method is proved by computer simulation in telephone channels.
