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. |

1. A transceiver for full-duplex communication, comprising:
a transmitter, having
a first oscillator circuit, for generating a transmit-carrier signal; anda 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; and a receiver, having:
a second oscillator circuit, for generating a receive-carrier signal at a different frequency to the transmit-carrier signal; anda second mixer for down-converting a received signal by mixing it with the receive-carrier signal, wherein 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 comprising an interference cancellation circuit adapted to generate, based on the data signal 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. |
