Abstract: According to at least one aspect, a communication system is provided. The communication system includes a first switch device configured to receive a first plurality of radio frequency (RF) signals detected by an antenna array and provide an RF signal selected from among the first plurality of RF signals to a receiver circuit, the first plurality of RF signals comprising a first RF signal in a first frequency range and a second RF signal in a second frequency range that is different from the first frequency range; and a second switch device configured to receive a second plurality of RF signals detected by the antenna array and provide an RF signal selected from among the second plurality of RF signals to the receiver circuit, the second plurality of RF signals comprising a third RF signal in the first frequency range and a fourth RF signal in the second frequency range.

Abstract: A radio frequency (RF) communication assembly includes an RF communication circuit and a compensator apparatus. The compensator apparatus receives an input including an I-component of a pre-compensated signal, a Q-component of the pre-compensated signal, and encoded operating conditions of the RF communication circuit. The RF communication circuit includes RF circuit components causing signal impairments. The compensator apparatus perform neural network computing on the input, and the RF communication assembly generates a compensated output signal that compensates for at least a portion of the signal impairments.
