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.

Claim (Index 13):
A wireless receiving method, comprising:\n calculating a first eigenvector corresponding to a largest eigenvalue of a covariance matrix of each of the received signals of radio waves from a wireless transmitter having a plurality of frequencies received by an antenna array; estimating angles of arrival of the radio waves having the plurality of frequencies; calculating an absolute value of an inner product of each first eigenvector and a steering vector corresponding to each of the angles of arrival as a similarity index; determining whether or not each of the angles of arrival is an outlier based on the index; and excluding an angle of arrival determined as the outlier from the angles of arrival, and determining an output angle of arrival.
