Abstract
An input signal from an external source is correlated to a spreading code which is indicative of the difference between first and second spreading codes which are out of phase with each other thereby to produce a correlated signal. The correlated signal is compared with first and second predetermined values to detect synchronization of the input signal with either one of the first and second spreading codes. Spreading code synchronization is achieved within a shortened period of time in a spread-spectrum communication system.
