Abstract

In a digital matched filter used as a correlator in a receiver in an SSC system, different bits of a received signal converted into a multi-bit signal are inputted into different correlators. After having weighted different correlation outputs, the different weighted correlation outputs are added together and weighting factors are varied, depending on a synthesized correlation output obtained by addition. When such a matched filter is used in an SSC system, it is possible to obtain precisely a desired signal without controlling transmission electric power.
