Abstract
In a direct sequence spread spectrum receiver, multiple correlators are provided for despreading a spread data signal and a spread pilot signal. During a sync acquisition mode, pilot demodulators are connected to the correlators, respectively, and during a subsequent tracking mode, data demodulators are connected to the correlators whose outputs are combined by an adder to produce an output for the receiver. Despreading codes of different phase positions are generated and supplied to the correlators, respectively. During the sync acquisition mode, the phase position of each despreading code is successively shifted and high correlation values are determined from the outputs of the pilot demodulators. During the tracking mode, the phase positions of the despreading codes are set according to the high correlation values.
