Abstract
An array antenna system of a wireless base station in CDMA mobile communications has a beam former for forming a plurality of electric beams by applying beam forming to multipath signals received by a plurality of antenna elements of an array antenna and inputting the beams to despreading/delay-adjusting units (fingers) provided for respective path of multipaths. Each finger despreads each of the plurality of beams input thereto. A beam selector selects despread signals for which desired signal components are large from all beams of all paths, a combiner weights and combines the selected despread signals, and an decision unit decides data based upon the combined signal.
