A radio communication apparatus includes a received beam generating section 12 for generating received beams beam 0 and beam 1, which are orthogonal to each other and spatially separated, by assigning weights to received signals fed from receiving antennas 11 by using received beam weights; path search sections 13 and 14 each for outputting path information when the received beams beam 0 or beam 1 includes a spread signal spread by a known spreading code; a demodulating section 16 for outputting demodulation data by receiving the received beams beam 0 and beam 1 and by RAKE combining them in response to the path information; and a feedback control section 15 for outputting selection information 101 by selecting a transmission beam to be transmitted in response to the path information and the phase difference between the received beams beam 0 and beam 1 fed from the demodulating section 16.
