Patent ID: 11990683

Abstract:
A wireless communication device (500) according to the present disclosure includes a plurality of antennas (520#n), a plurality of transmitter-receivers (TRX#n) that are provided in association with each of the plurality of antennas (520#n), and each include a transmitter (TX#n) and a receiver (RX#n), a calibration transmitter-receiver (CAL-TRX), a distribution synthesis unit (530), and a control unit (510). The control unit (510) causes a transmission calibration signal to be transmitted to each transmitter (TX#n) to be orthogonalized in frequency for each transmitter (TX#n). Each transmitter (TX#n) sends the transmission calibration signal being orthogonalized in frequency. The distribution synthesis unit (530) synthesizes the transmission calibration signals being transmitted from the transmitters (TX#n), and transmits the synthesized signal to the calibration transmitter-receiver (CAL-TRX).
