摘　　要：首先简述了逆系统原理,然后描述了用MATLAB软件仿真实验得出DCT-LMS自适应均衡滤波器的收敛性和稳态性与滤波器长度和信道失真参数之间的定量关系,为此构建了有实际意义的系统仿真模型、做出了仿真实验结果并分析了仿真实验结果的意义,最后对DCT-LMS算法性能与传统LMS算法的性能进行了分析比较.First, the principle of the inverse system is introduced in this paper. Then, the quantificational correlation among the stability and astringency of the DCT - LMS adaptive equalization filter and two important parameters of filter length and channel distortion are given through simulation experiments done with MATLAB software. Based on these, a practical simulation model is set up, the simulation results are obtained and analyzed. At last, the performance of the DCL - MS algorithm and the traditional LMS algorithm is compared.
