New Constant Modulus Blind Equalization Algorithm Based on Variable Segment Error Function
Yecai Guo · Jisuanji fangzhen · 2007
In order to overcome the slow convergence rate and large steady state error of Constant Modulus Algorithm(CMA),a new CMA based on a variable segment error function was proposed.This blind equalization algorithm can change the characteristic of error function by adjusting the segment position,so it can obtain a suitable odd symmetric error function used in channel equalization.The efficiency of the method is proved by computer simulations with two-twist underwater acoustic channel and negative acoustic gradient underwater acoustic channel.
