A communication system includes an echo canceller and double-talk detector. ø 本发明提供一种双方交谈侦测方法与装置,可应用在一迴音消除系统中侦测一双方交谈状态之通讯系统中。
Upon detection of double-talk status, operation of the echo canceller is suspended. 当侦测到一双方交谈状态时,双方交谈侦测装置能够停止迴音消除系统的调整。
The echo canceller includes an adaptive finite impulse response filter that generates an adaptive filter weight vector. 此迴音消除系统由一适应性有限脉冲响应滤波器所组成,它能产生一组适应性滤波器权值向量。
