| 摘 要： | 盲信号分离的依据通常是信号的独立性或利用它们的高阶累积量。考虑了双通道的盲分离问题，提出了一种基于相关函数的盲分离准则。证明了在源信号不相关的条件下，可以实现源信号的盲分离。并给出了一种可直接求解二次方程组的盲分离算法。

| Abstract: | Blind separation of source signals usually relies either on the condition of statistically independence or involving their higher-order cumulants. The model of two channels signal separation is considered. A criterion based on correlation functions is proposed. It is proved that the signals can be separated, using only the condition of noncorrelation. An algorithm is derived, which only involves the solution to quadric nonlinear equations. |
