当处理混合语音信号时,传统的立体声回波抵消技术不具备修正参数的能力。因此,传统的立体声回波抵消技术对于信号传输的可靠性存在很大的问题,论文中,我们提出一种基于盲信号分离方法(BSS)的立体声回波抵消技术。在我们提出的系统中,我们通过分离回波信号和说话人的语音信号来达到移除回波信号的目的。结果证明,本方法对于传输信号的可靠性有明显的提高。 Traditional stereo echo cancellation techniques do not have the ability to modify parameters when working with mixed voice signals. Therefore, the traditional stereo echo cancellation technology has great problems for the reliability of signal transmission. In the paper, we propose a stereo echo cancellation technique based on the blind signal separation method (BSS). In our proposed system, we achieve the purpose of removing echo signals by separating the echo signal from the speaker’s speech signal. The results show that this method has obvious improvement on the reliability of the transmitted signal.
