Patent ID: 7505509

Claim:
A receiving apparatus comprising a receiving section for performing RAKE receiving with a plurality of fingers and a searcher for detecting path timings to be given to each of the fingers of the receiving section, each of the plurality of fingers of the receiving section comprising a first beam former for performing beam forming based on signals received from a plurality of antennas forming an array antenna, wherein the searcher comprises: a plurality of correlators, each for performing correlation processing on the signals received from a respective one of the plurality of antennas; a delay circuit placed after the plurality of correlators receiving outputs of the plurality of correlators; a direction-of-arrival calculator for estimating direction of arrival based on the outputs of the plurality of correlators; a second beam former for performing beam forming on outputs of the delay circuit in accordance with an estimation result supplied from the direction-of-arrival calculator; and a path detector for detecting the timing based on an output of the second beam former, wherein the direction-of-arrival calculator performs complex multiplication between adjacent ones of the plurality of antennas to determine the direction of arrival estimation result.
