Correlation with a spreading code is done for each of the signals received by a plurality of antennas forming an array antenna (10); then, beam forming (18) is performed using the result of the correlation, and a delay profile is generated (20, 22, 26) from the result of the beam forming, thereby achieving accurate path detection (26). DOA information obtained for the beam forming (18) can also be used as an initial value to be given to a beam former (33) in a received signal processor (14).
