Claim Text:
1. A method comprising: obtaining baseband transmit data; generating a multicarrier transmit signal using the baseband transmit data; transmitting the multicarrier transmit signal from a transmit antenna; receiving a composite receive signal at a receive antenna, the composite receive signal having a component associated with the multicarrier transmit signal; performing analog RF cancellation to reduce a level of the multicarrier transmit signal component of the composite receive signal to generate an RF cancelled receive signal; processing the RF cancelled receive signal in an RF receiver to generate a digital receive signal; and performing digital cancellation on the digital receive signal to reduce remnants of the multicarrier transmit signal therein, wherein performing digital cancellation includes performing cancellation on a subcarrier by subcarrier basis, wherein performing digital cancellation comprises modifying amplitudes and phases associated with individual subcarriers of the digital receive signal in accordance with a digital cancellation signal.
