基于坐标变换的常数模盲均衡新算法
New Constant Modulus Algorithm for Blind Equalization Based on Coordinate Transformation
摘要
Abstract
by studying the characteristics of the constellations for different transmitted signals, we modify the cost function of Constant Modulus Algorithrn (CMA) and propose a new CMA based on coordinate transformation. The proposed algorithm changes the modulus of transmitted signals to zero, which can lead the output error to converge to zero even for nonconstant modulus signals. Furthermore it can achieve blind equalization without any priori statistical information of transmitted signals. Theoretic analysis and computer simulation results demonstrate that the proposed algorithm offers high performance.关键词
