WIRELESS COMMUNICATION DEVICE AND ESTIMATION METHOD

摘要

A wireless communication device includes: a plurality of antennas configured to receive a radio wave; a processor configured to execute a program; and a memory configured to store the program, wherein the processor preforms operations to: measure reception strength of a radio wave of an estimation target at each of the plurality of antennas; executes first calculation processing of calculating first correlation coefficients of antenna pairs among the plurality of antennas and calculating a second correlation coefficient of the plurality of antennas by using the first correlation coefficients for each of a plurality of direction-of-arrival candidates of the radio wave; and estimates a first direction of arrival of the radio wave of the estimation target based on the second correlation coefficient for each of the direction-of-arrival candidates.
