基于独立分量分析的单通道语音降噪算法研究
Research of Single Channel Speech Noise Reduction Algorithm Based on Independent Component Analysis
【摘要】 简要介绍了有关独立分量分析的基本理论和算法,文中提出一种方法,巧妙地从单路信号中生成两路信号,然后对其进行独立分量分析(ICA),克服了无法直接对单路信号进行独立分量分析的困难,实现语音增强。
【Abstract】 In the paper,a smart technique to generate two signals from one single signal is presented,which can be processed by using ICA.Simulation results show that the ICA-based method can improve SNA in high noise condition,and keep good intelligibility.
