Apparatus and method for controlling the operational state of an echo canceller

摘要

An apparatus for processing wireless telecommunications is provided. The apparatus includes an echo canceller module. An echo canceller module controller is connected to the echo canceller module. The echo canceller module controller can receive echo canceller data, and can turn the echo canceller module on when the echo canceller data indicates that echo cancellation is required, such that echo cancellation may be controllably turned on only when it is needed.
