Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a frequency error detection circuit. SOLUTION: I, Q signals from A/D converters 10, 9 are given to a phase detection circuit 32, by which phase orthogonal detection outputs is detected. The phase detected by the phase detection circuit 32 is given to a subtractor 34 without any modification and delayed therein by a valid symbol period and the delayed phase signal is given to a subtractor 34. The subtractor 34 obtains a difference between two inputs. An orthogonal detection output for a guard period and that for an end period for the valid symbol period are substantially identical to each other. Thus, an output of the subtractor 34 indicates a carrier frequency error. The frequency error signal from the subtractor 34 is outputted via a gate circuit 35. Thus, the oscillated frequency of a local oscillator 8 is controlled to obtain carrier synchronization.  A frequency error detection circuit 31 does not include a multiplier and an accumulator and then its circuit scale is small.
