摘    要:将源信号的先验知识以参考信号的形式引入到独立分量分析(ICA)学习算法中,从混合信号中仅提取期望的源信号。依据语音信号传播机理和Bessel函数展开系数对语音信号的表征能力,给出基于Bessel函数展开的参考信号构建方法,从混合语音信号中提取出期望的语音信号。仿真和性能分析结果表明,该方法能在噪声干扰的情况下达到语音增强的目的。

关 键 词:盲源分离  独立分量分析  参考独立分量分析  Bessel函数  经验模式分解  语音增强

Abstract:Independent Component Analysis with Reference(ICA-R) can extract only desired source signal from mixtures of all source signals by incorporating prior information into the learning algorithm as reference signal. The rule of voice signal transmission and Bessel function expansion can describe voice signals. This paper applies Independent Component Analysis with Reference(ICA-R) to extract a target voice signal from mixtures of all source signals by constructing a proper reference signal with Bessel function expansion, computer simulation results and performance analysis demonstrate the method can get better voice enhancement effect under noise interference situation.
Keywords:Blind Source Separation(BSS)  Independent Component Analysis(ICA)  ICA with Reference(ICA-R)  Bessel function  Empirical Mode Decomposition(EMD)  voice enhancement
