摘要
针对现有的最小二乘恒模盲分离算法虽然能实现源信号分离但分离信号间仍存在相关性的问题,在建立均匀线阵接收模型和分析现有算法的基础上,提出了一种将阵列结构和已有算法相结合的修正小二乘恒模盲分离算法,并进行了实验仿真。仿真结果表明,修正算法有效地降低了分离信号间的相关性,将分离结果用于信号测向,实现了对空间信号源的高分辨率测向。
To solve the problem of a similarity between separated sources in the available least square constant modulus blind signal separation algorithm,a nove l least square constant modulus blind signal separation algorithm based on the u niform linear array（ULA）model and the available algorithm is presented here.Simu lation results show that the algorithm can weak the similarity effectively compa red with the available algorithm.The algorithm can also be applied in direction finding to achieve high resolution direction finding of spatial signal sources.
