In an adaptive array antenna reception apparatus, radio reception sections (102a, 102b, . . . , 102n) convert RF signals from antenna elements (101a to 101n) into baseband signals (118a, 118b, . . . , 118n) and output them. In response to the converted baseband signals, a searcher section (103) detects the position (timing) of a path for each of the beams based on the antenna elements (101a to 101n). A Finger section (104) performs despreading at the timing detected by the searcher section (103), forms beams by using an adaptive algorithm, and maximum-ratio combines the beams. In this manner, when paths coincide with each other on the time axis, such paths can be discriminated in accordance with the positions (timings) of the paths. Therefore, there is no need to re-allocate the paths when a delay information difference is detected. This improves the follow-up characteristics of beams and communication quality.
