Abstract: The present disclosure relates to a transceiver comprising a transmitter with transformation circuitry configured to transform a frequency-domain transmit symbol from frequency domain to time domain to generate a time-domain transmit signal, a receiver with inverse transformation circuitry configured to transform a time-domain receive signal from time domain to frequency domain to generate a frequency-domain receive symbol, and self-interference cancellation circuitry configured to modify the frequency-domain receive symbol based on at least one frequency-domain transmit symbol and a frequency-domain crosstalk channel estimate of a crosstalk channel between the transmitter and the receiver.
