| Abstract: | 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. |
