Method And Apparatus For Cancelling Interference In A Transceiver

Abstract: A method and apparatus for cancelling an interference in a received signal. The apparatus may include a plurality of receivers and one or more transmitters. The first receiver is configured to process a received signal. The first receiver includes a mixer to down-convert the received signal using a first local oscillator signal having a first frequency. The received signal includes a wanted signal and an unwanted signal. The second receiver is configured to process the received signal and generate an interference reference signal. The second receiver includes a mixer to down-convert the received signal using a second local oscillator signal having a second frequency. The apparatus includes an interference canceller configured to cancel, in a digital domain, at least in part interference caused by non-linear characteristics of the first receive chain in a presence of the unwanted signal from the down-converted received signal by the first receive chain.
