ABSTRACT:
A tracking circuit includes a plurality of phase sections each corresponding to different phases of a despreading code. Each of the phase sections includes a correlator for producing a correlation value between a reception signal and a corresponding phase of the spreading code and a power calculator calculates a power value from the correlation value. A comparator compares power values received from the phase sections to produce a comparison result. A controller selectively activates the plurality of phase sections based on the comparison result, allowing power consumption to be reduced.
