An Algorithm Based on Nonlinear PCA for Blind Separation of Convolutive Mixtures
Author(s): 
Pages: 1009-1012
Year: Issue:  5
Journal: ACTA ELECTRONICA SINICA

Keyword:  盲信号分离卷积混合非线性PCA;
Abstract: 本文针对卷积混合的盲源分离,首先提出了一种基于非线性主成分分析(PCA)的准则,然后推导出了一种递推最小二乘(RLS)算法.该算法为时域盲源分离算法,分为两个阶段,第一阶段为混合信号的白化,第二阶段为基于白化信号的RLS迭代.新算法不存在频域算法在每个频点的幅度与次序不确定性的问题,具有较快的收敛速度.文中最后通过仿真试验验证了本文算法的有效性.
