Abstract
A method and apparatus for cancelling interference of an interfering transmit signal. The method includes the steps of (a) transmitting an RF transmit signal from a transceiver, (b) optically modulating the RF transmit signal, (c) optically modulating a RF receive signal; (d) demodulating an optical signal back to an RF signal using an optical-electrical balanced receiver and directing to the transceiver, and (e) demodulating the optical transmit signal back to RF transmit signal.
