Abstract
A wireless receiver includes an antenna array and processing circuitry. The antenna array receives radio waves from a radio wave radiator to output received signals. The processing circuitry calculates similarity indices based on (1) a first eigenvector corresponding to a largest eigenvalue of a covariance matrix of each of the received signals, and (2) a degree of similarity between the first eigenvector and a steering vector of a single wave, estimates angles of arrival of the received signals, and determines an output angle of arrival from the estimated angles of arrival of the received signals.
