adaptive recursive echo canceller

At first a brief introduction of current detection algorithms based on temporal profile analysis is addressed,and then noise and target s pixel temporal profile variance is thoroughly studied,finally a detection algorithm based on adaptive recursive variance filter(ARVF) is proposed.

首先对现有基于像素时域剖面分析的检测算法进行了简要的综述,然后根据不同像素的时域剖面模型对其时域方差变化特性进行了详细分析,提出了一种基于自适应递归方差滤波器的检测算法。

In an adaptive echo canceller,the detection algorithm able to distinguish echo pass change(EPC) from double-talk(DT) is vital to ensure that adaptive filter tap coefficients are updated in case of EPC and frozen during the DT period.

自适应声回波对消器中,可区分回波通道变化EPC(Echo Pass Change)和双端话音DT(Double-Talk)的检测算法非常重要,以确保自适应滤波器在EPC时更新权系数,在DT期间冻结权系数。
