盲信号提取的神经网络方法

On Neural Network Method for Extraction of Blind Signals

采用神经网络方法 ,在对于混合矩阵的秩知道一些先验信息的条件下 ,对于检测信号少于盲信号的问题 ,从理论上给出了提取盲信号的充分与必要条件 ,根据这个条件 ,从检测信号中能够提取出某些盲信号

By using neural network method, under the condition of that some information about rank of the mixture matrix is known, we present a condition of extraction. By using the condition, one can extract some blind signals from the observed signals, when the number of observed signals less than the number of blind signals. A theoretical necessary and sufficient condition of extractability is given. The structure of the neural network and the method of extraction are proposed in detail.
