Abstract: A wireless communication system including a phased array comprising a plurality of antennas configured to emit a respective radio wave based on a respective antenna signal. Further, the system includes a plurality of power amplifiers each coupled to one of the plurality of antennas via a feed line and configured to output the antenna signal to the feed line. Also, the system includes a plurality of directional couplers each coupled into one of the feed lines and comprising a third port configured to output a fraction of a power received at a first port coupled to the power amplifier via the feed line, likewise a fourth port configured to output a fraction of a power received at a second port. Additionally, the system includes switching circuitry configured to alternately couple the third port to a first feedback receiver, and to alternately couple the fourth port to a second feedback receiver.

Abstract: A system and method for digital correction for a dynamically varying non-linear system. The system includes a correction circuitry including at least one look-up table (LUT). The correction circuitry is configured to receive an input signal and modify the input signal to be processed by the non-linear system using at least one LUT to correct non-linearity incurred by the non-linear system. The at least one LUT is addressed by a magnitude or power of the input signal and a dynamically varying parameter associated with the input signal. The dynamically varying parameter may be one of average signal power of the input signal, a differential of the average power of the input signal, a directional beam index, or temperature.
