针对复杂环境下的线性混叠信号,给出了一种基于广义特征分解的盲信号分离方法。在信号数目未知的情况下,该方法利用广义特征分解即可获得混叠矩阵,无需进行常规的迭代运算即可实现对线性混叠信号的分离。实验证明了该方法的可行性和有效性。

For the linear mixtures under complicated surroundings, a new blind signal separation method based on generalized eigen-decomposition is proposed. In the case of the number of the signals unknown, the method can acquire the demixing matrix by using the generalized eigen-decomposition. And the hnear mixtures can be separated without using generalized iterative operation. The experiment indicates that the meth6d is feasible and effecti,~e.
