WIRELESS COMMUNICATION DEVICE, CONTROL CIRCUIT, STORAGE MEDIUM, AND SIGNAL PROCESSING METHOD

WIPO Patent Application WO/2023/053193

A1

A wireless communication device (10) for processing a reception signal that is received using a plurality of antennas and that includes a plurality of transmission signals, which have the same signal format and are transmitted from a plurality of transmission devices using a common frequency band, the wireless communication device (10) comprising: a control coefficient determination unit (103) for determining a directivity control coefficient of the reception signal so that at least one of an arrival time difference, a frequency difference, and a reception power difference between the plurality of transmission signals included in the reception signal increases; a directivity control unit (104) for controlling the directivity of the reception signal using the directivity control coefficient; a synchronization unit (105) for estimating the arrival time and frequency of a signal to be demodulated, which is one of the plurality of transmission signals included in the reception signal; a demodulation unit (106) for demodulating the signal to be demodulated, on the basis of the estimation result; a replica generation unit (107) for generating a replica of the signal to be demodulated, on the basis of the estimation result and the demodulation result; and an interference cancellation unit (102) for subtracting the replica from the reception signal and outputting a subtraction result.
