<p>A matched filter (MF) (110a) of a path searching unit (110) of a searcher (108) subjects a signal received by an AAA (Adaptive Array Antenna) to a spectrum despreading processing. An electric power adding circuit (110c) adds the power of the signal produced by performing common mode addition of the despread signal, and outputs the resultant signal to a delay profile defining circuit (110d) and a threshold judging circuit (111). The outputs from the threshold judging circuits (111) are outputted to a synthesizing circuit (112). The synthesized power value produced by the synthesizing circuit (112) is outputted to a delay profile defining circuit (113). A delay profile is defined based on the synthesized power value. A finger assigning circuit (114) determines a despreading timing for an AAA reception weight operation according to the delay profile.</p> |
