摘要
The invention relates to a method of preventing an adaptive echo canceller from diverging in a noisy environment. The method comprises steps of: determining an average noise level (-45 dBmO) in the echo path, determining an attenuation (Ae) of the echo path and preventing an adaptation of the echo canceller, if the level of the signal (x(i)) to be transmitted to the echo path and causing echo (r(i)) is lowered to a predetermined threshold level, which is to the extent of a preset margin and the echo path attenuation above the average noise level.
