1. A wireless transmit/receive unit (WTRU) comprising:

  • (a) a modem;

    (b) a transmitter that unintentionally generates a corrupted signal including a self-interfering signal component and a desired signal component;

    (c) a self-interference canceller (SIC) configured to receive a transmitter noise reference signal including the self-interfering signal component, to receive the corrupted signal including the self-interfering signal component and the desired signal component, and to output a correction signal that resembles the self-interfering signal component; and

    (d) an adder configured to subtract the correction signal from the corrupted signal to generate a processed signal that is input to the modem.
