Performance Comparison of Blind Equalization Algorithm
Wenjun Su, Haitao Chen · 2017
Theory and method of Baud spaced equalizer (BSE) and fractionally spaced equalizer (FSE) based on constant modulus algorithm (CMA) are reviewed.For the un-changed characteristics channel, adaptive constant modulus algorithm can achieve good performance in blind equalization.But the tracking ability of adaptive constant modulus algorithm gets worse while the char-acteristics of channel changes more quickly.Fractional-ly spaced equalizer can achieve distortion compensation in the received signal and better performance than baud-spaced equalizer, because aliasing caused by under sampling is avoided.
