Abstract:
1. A correlator for generating a correlation signal representing correlation between a received signal and spreading codes, comprising: despreading means for despreading an inphase component and a quadrature component of said received signal using said spreading codes into despread signals; conversion means for converting said despread signals into synchronized signals which are inphase with each other; first averager means for averaging said synchronized signals over a predetermined period into first average signals; first power calculation means for calculating first power information from said first average signals; second power calculation means for calculating second power information from said despread signals; second averager means for averaging said second power information over said predetermined period into second average signals; multiplication means for multiplying one of said first power information and said second average signal by a factor and outputting a result of the multiplication as an auxiliary signal; and addition means for adding said auxiliary signal and another of said first power information and said second average signal and outputting a result of the addition as said correlation signal.
