Abstract
There is disclosed a synchronous circuit and a receiver in which a long code for use in communication can be determined in a short time, and circuit scale can be reduced. Upon receiving input of a data stop signal from a control unit, a matched filter continues to hold the signal held at the time, performs a product sum operation of a spreading code successively inputted from a spreading code generator and the held signal, and successively outputs correlation signals in the synchronous circuit and the receiver.
