FEEDBACK CANCELLATION SYSTEM AND METHOD |
摘要 |
A system and method for detecting antenna coupling and for providing feedback cancellation in response to the antenna coupling includes a signal feedback cancellation circuit configured to be coupled between a signal receiver and a signal transmitter. The feedback cancellation circuit is responsive to received signals, amplified signals and the detection of signal coupling between a receiving antenna any transmitting antenna, for providing a feedback cancellation signal to a signal amplifier. The feedback cancellation circuit may employ time domain or frequency domain methods. In the case of a time domain method, the feedback cancellation circuit may further include a White noise generator which serves to the tune or adjust the feedback cancellation circuit.
