ABSTRACT:
By taking the product of two correlators, the present invention realizes a synchronizing method having good tracking characteristics and not requiring balance between pairs of correlator signals in a receive system for a spread spectrum communications system for a carrier band. A correlator 1 correlates the received signals and the PN signals from a PN signal generator 6 and a correlator 2 correlates the received signals, PN signals from a PN signal generator 6, and clock signals from a VCC 5. The signals of the correlator 1 and the signals of the correlator 2 are multiplied by a multiplier 3, and are passed through a low pass filter 4 so as to obtain and control signals for clock control of PN signals.
