文中提出一个基于线性即时混合类型的两步盲信号分离方案.该方案先利用接收信号的二阶统计特性对信号进行白化,然后利用常模算法对信号向量进行自适应的盲分离.为了使每一个输出端都能分离出一个独立的信号,文中提出一种基于正交约束的常模算法,仿真结果表明该算法不仅能使每个输出端收敛到一个独立的输入端,并且能使收敛速度加快.

A two stage blind signal separation scheme for instantaneous MIMO systems is presented.The method combines whitening and constant modulus algorithm(CMA)to separate the signal vector blindly and adaptively.In order to make each output extracts a single and different signal and speed the CMA convergence rate,an orthogonal constrained CMA is proposed.
