基于不相关性的非稳态信号解耦技术（Study of Non-stationary Signal Decoupling Based on Decorrelation）
解耦 非相关 非稳态信号 随机信号
2009/8/11
对两路非稳态随机实值信号通过一个线性未知系统后得到两路输出信号的解耦问题进行了探讨。首先建立了非稳态信号的两路输入、两路输出系统的数学模型，将系统的解耦问题转换成求解系统的解耦系数问题。然后对解耦系数的求解进行推导，并给出算法适用的必要条件是信号为非稳态和不相关。通过计算出的解耦系数将源信号从测得的输出耦合信号中分离。通过本算法对人工耦合成的两路信号进行了解耦，结果证明了本算法的正确性。最后将算法...
