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 15):
The wireless system according to  claim 14 , comprising a plurality of wireless receivers,\n wherein the plurality of wireless receivers each determine whether or not the determined output angle of arrival is to be used for tracking based on an amount of deviation between the determined output angle of arrival and a predicted estimate of the output angle of arrival, and track an angle of the wireless transmitter by using the output angle of arrival determined to be used for tracking, wherein the system uses results of tracking performed by the plurality of wireless receivers, and estimates a position of the wireless transmitter.
