Abstract
Systems and apparatuses include a sniffer circuit, a radio frequency processor, and a beamforming radio frequency integrated circuit. The sniffer circuit is structured to receive spurious signals from a sniffer antenna and self-jamming signals, and to produce an interference signal based on the spurious signals and the self-jamming signals. The radio frequency processor is structured to receive wideband signals from a plurality of radiating elements, receive the interference signals from the sniffer circuit, execute a subtraction from the wideband signals based on the interference signals, and produce desired signals. The beamforming radio frequency integrated circuit is structured to receive the desired signals from the radio frequency processor, execute beamforming operations, and produce an output signal.
