摘要: A communication system includes an echo canceller and double-talk detector. The echo canceller includes an adaptive finite impulse response filter that generates an adaptive filter weight vector. The double talk detector computes a squared norm of the filter weight vector and detects an increase of the squared norm in order to detect double-talk status. Upon detection of double-talk status, operation of the echo canceller is suspended.
