碩士 === 元智大學 === 電機工程學系 === 98 === Adaptive filters are applied in many applications such as echo canceling and adaptive equalizer. In digital communication, in order to cancel (Inter-symbol Interference, ISI) and noise, we can add the equalizer in receiver, as to communication system, ISI effect between the signal and the signal and noise, not only to make transfer signal distortion but also to make receiver discrimination mistake, Make the signal received make a mistake, the data are incorrect, receiver equalizer can cancel ISI effect and noise, the improvement of correct rate of the data. In this thesis, laboratory research NNPVSS algorithm combine structure of equalizer, we simulation investigate algorithm on MATLAB, Verify their exactness and performance. The simulation of results is with indicator of (Mean Square Error, MSE) and (Bit Error Rate, BER) to observe, the algorithm of laboratory research can get the performance slightly better than NLMS and NPVSS.
