发明名称 METHOD AND APPARATUS FOR ADAPTIVE ECHO AND NOISE CONTROL
摘要 An method (500) and apparatus (100) for adaptive echo and noise control. A signal can be received at an input (140) to a communication or electronic device. Background noise in the signal can be determined. The order of noise suppression and echo cancellation can be adaptively determined (110) based on the background noise in the signal. Adaptively determining the order of noise suppression (230) and echo cancellation (220) can be performed by comparing the background noise to at least one threshold, performing echo cancellation prior to noise suppression on the signal if the background noise is below the at least one threshold, and performing noise suppression prior to echo cancellation on the signal if the background noise is above the at least one threshold.
