| 1. | The problem of source separation - separation of one or more desired signals from mixed recordings of multiple signals - has traditionally been approached by using multiple microphones , in order to obtain sufficient information about the incoming speech signals to perform effective separation . typically , no prior information about the speech signals is assumed , other than that the multiple signals that have been combined are statistically independent , or uncorrelated with each other 但是要在计算机上实现人耳的这个能力是非常困难的,这就是计算机模拟人耳功能的盲信号分离问题( bss ) ,即要从混合在一起的声音信号中分离出一个或者多个感兴趣的声音信号出来,而事先我们对混合在一起的声源信号的情况是根本不知道的。 |
