Abstract
An adaptive electronic transmission signal cancellation circuit for separating transmit data from receive data in a bidirectional communication system operating in full duplex mode is disclosed. A transmit signal cancellation circuit is coupled to a transmit signal path and a receive signal path of the communication system, where the transmit signal cancellation circuit is configured to generate a cancellation signal corresponding to a transmit signal. The cancellation circuit is further configured to apply the cancellation signal on the receive signal path for preventing the transmit signal from being asserted to the receive signal path. The cancellation signal comprises a first component and a second component, where the first component represents a mirror image of the transmit signal and the second component represents a direct image of the transmit signal.
