A multiplying and measuring circuit 6 multiplies the signal q(t) by reference signals s(t), c(t) generated from a reference signal generator 9 and executes prescribed processing for the multiplied results. A circuit 19 outputs a phase error signal Z based on outputs from the circuits 6 and the signal Z is supplied to the circuit 9 to correct the phase error of a locally generated carrier sigraal. A circuit 20 locks the phase of a data clock pulse 2D generated from a clock pulse generator 36 at an incoming baud rate. Consequently the difference of sampling points in data outputted from a data restoring circuit 18 can be reduced.
