Abstract:
A bidirectional transceiver includes a transmitter and a receiver that respectively transmits a local signal to and receives remote signal from a common bidirectional communication channel, thus the bidirectional channel signal is the superimposition of the local and remote signals. The bidirectional transceiver also includes a transmit canceller that substantially removes the local transmitted signal from the superimposed signals on the bidirectional channel before the local receiver. The remote signal is transmitted by a remote transceiver over the bidirectional channel. A sampling phase is set, based on timing information in the received remote signal, and the received signal is sampled. Timing relation of transitions in the local transmit signal relative to the receiver sampling phase is set such that transmit signal cancellation is optimum at receiver sampling phase, by changing the delay applied to the local transmit signal. To keep the timing relation of the local transmit signal relative to the remote transceiver, a second delay is applied to the local transmit signal before transmission into the bidirectional channel that provides a delay substantially same as the first delay but opposite in direction.
