Abstract
An SSC receiver, in which desired information is restored by means of a correlator, which forms the correlation between a received PN code included in a received signal and a reference PN code included in a reference signal, is disclosed, wherein it is so constructed that the output of the correlator stated above is inputted in pattern judging means, that in the case where no accordance with a predetermined judgment pattern is obtained, when a certain period of time has elapsed, judgment patterns, which are analogous to the predetermined judgment pattern stated above, are switched over one after another, every time a predetermined period of time has elapsed, and that the position, where the two codes are in accordance with each other, is set correctly by controlling the phase of the reference PN code by using the output, when the output of the correlator described above is in accordance with either one of the judgment patterns.
