提出了一种新的病态混叠盲源分离算法。算法首先对观察信号进行预处理，把多余的观察信号剔除，使预处理后的混叠矩阵A是行满秩的；
It is proposed a new blind separation algorithm of ill-condition mixed sources. Observed signals are pre-processed through eliminating redundancy signals so that mixed matrix A is row full rank.
字典定义失明为“没有视觉”，但是失明实际分为很多级别。我们把这个矩阵的秩定义为它所包含的线性无关行的数目。
Dictionaries define blindness as "being without the sense of sign, " but there are many degrees of blindness.
