Abstract

PURPOSE:To eliminate the need for a complicated loop system and thus simplify the constitution of a receiver of spread spectrum communication system, by adapting a synchronous circuit that operates on a passive working theory. CONSTITUTION:The signal received through an antenna 6 is led to a multiplier 17 by a line 15 and at the same time receives a delay of dDELTA by a delaying circuit 16. The signal delayed throuth the circuit 16 is applied to the multiplier 17 and multiplied by a received signal to be supplied to an LPF18. Then the difference component signal of the multiplied signal is delivered through the LPF18 to receive a phase matching through a delaying circuit 19. Owing to such constitution, no complicated loop system is required for a receiver in a spread spectrum communication. And a synchronous circuit is used to simplify the constitution of a receiver.
