Abstract
A communication device is capable of estimating an incoming wave number with high accuracy. A communication device includes an antenna and circuitry configured to calculate an arrival direction of a reception signal received from the antenna in a case of a predetermined incoming wave number based on the reception signal and the predetermined incoming wave number, calculate an incoming signal for each of one or more arrival directions in a case of a certain incoming wave number based on the incoming wave number and the one or more arrival directions, and estimate an incoming wave number of the reception signal based on levels of the incoming signals in a plurality of arrival directions.
