摘要
盲分离算法被广泛应用于语音信号处理领域中 ,本文给出了一种改进的基于高阶累积量的盲信号分离算法并且被用来进行双路语音增强 ,本文还提出了最速下降法滤波器抽头系数更新算法 .模拟和实际录音的实验表明所提方法的有效性 .
Blind source separation algorithms are widely used in speech signal processing field.An improved Blind Source Separation method based on cumulants is proposed and implemented in a dual-channel speech enhancement application.The steepest-descend procedure is used in the adaptation of decoupling filters.Simulation and real-world experiments yield good results,which proved the effectiveness of the proposed approach.
