Title:
COMMUNICATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/210479
Kind Code:
A1
Abstract:
Provided is a communication device which make it possible to estimate an incoming wave number at high accuracy. The communication device 10 comprises: an antenna 101; an incoming direction calculation unit 103 which calculates an incoming direction of a reception signal in the case of a prescribed incoming wave number on the basis of the reception signal received from the antenna 101 and the prescribed incoming wave number; an incoming signal calculation unit 104 which calculates an incoming signal for each incoming direction in the case of a certain incoming wave number on the basis of the incoming wave number and the incoming direction; and an incoming wave number estimation unit 106 which estimates the incoming wave number of the reception signal on the basis of the levels of incoming signals in a plurality of incoming directions.
