摘要

结合信号星座图特点

对常数模算法的代价函数进行修正

提出了基于坐标变换的常数模盲均衡新算法.该算法通过坐标变换将发射信号的模值转换成零

从而克服了常数模算法在对非常模信号进行均衡时

输出误差无法收敛至零的缺点;并且该算法可以在未知发射信号调制类型的情况下完成均衡.理论分析和仿真结果证明了新算法的优良性能.

Abstract

by studying the characteristics of the constellations for different transmitted signals

we modify the cost function of Constant Modulus Algorithm (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.
