Abstract: A transceiver for full-duplex communication. The transceiver comprises: a transmitter and a receiver. The transmitter has a first oscillator circuit, for generating a transmit-carrier signal; and a first mixer, for up-converting a data signal to be transmitted by mixing it with the transmit-carrier signal, said data signal comprising a plurality of data symbols. The receiver has: a second oscillator circuit, for generating a receive-carrier signal; and a second mixer for down-converting a received signal by mixing it with the receive-carrier signal. The first oscillator and second oscillator are controlled such that there is a predetermined phase relationship between the transmit-carrier and receive-carrier signals at the start of each transmitted data symbol. The transceiver further comprises an interference cancellation circuit adapted to generate, based on the data signal to be transmitted and the predetermined phase relationship, an estimate of an interference component present in the received signal, and to compensate for the interference using the estimate.

Abstract: A wired communications device configured to: receive a spread-spectrum timing-reference signal through a wired communications medium, from a second wired communications device; detect a code-phase of the received timing-reference signal; and transmit data to the second device through the wired communications medium, with a timing that is defined relative to the detected code-phase. Also provided is a master device configured to communicate with the wired communications device. The master device is configured to generate and transmit a spread-spectrum timing-reference signal to one or more first devices, through a wired communications medium and to receive, through the wired communications medium, data transmitted by the one or more first devices.
