Abstract: The present application a digital self-interference residual cancellation method that adjusts a magnitude of a sampled transmit signal based on compared magnitude and phases associated with tones. The digital self-interference residual cancellation method may follow an analog carrier cancellation stage where the digital self-interference residual cancellation is based on a determination of the channel circuit response used to control an infinite impulse response filter which can compensate using both poles and zeroes.

Abstract: In a wireless communication system, a method for configuring multiple antennas of a receiver may include configuring a primary antenna of the multiple antennas with a narrow band filter passing a selected uplink channel, and configuring a secondary antenna of the multiple antennas with a broad band filter passing multiple uplink channels. The receiver may sense the power of the multiple uplink channels received via the secondary antenna for use in controlling downlink power. Broad band configuration of the secondary antenna may be intermittent, interspersed with a narrow band filter configuration for diversity reception. The receiver may determine which of the multiple antennas is primary by sensing which antenna is receiving the strongest signal on the selected uplink channel. Different levels of automatic gain control may be applied to signals from respective different ones of the multiple antennas.
