Abstract
A receiver circuit is disclosed. The receiver circuit includes one or more receiver antennas configured to receive a plurality of RF signals transmitted from a transmitter circuit including one or more transmit antennas, an RF chain configured to generate a plurality of digitized samples of the received RF signals, and a controller configured to receive the digitized samples, to calculate a plurality of additional samples, and to calculate a measured angle of arrival or angle of departure (AoA or AoD) of the RF signals based on the digitized samples and the calculated additional samples.
Claims20
A receiver circuit, comprising:
- one or more receiver antennas configured to receive a plurality of RF signals transmitted from a transmitter circuit comprising one or more transmit antennas;
