Abstract
A beat signal normalizing section in a correction control section normalizes a group of sampling data of an input beat signal in one processing group. A phase amount measuring section calculates an amount of phase change of each sampling data. A correction control value calculating section compares the actually measured amount of phase change of each sampling data with an ideal amount of phase change of each sampling data and generates correction voltage data such that the actually measured amount of phase change matches with the ideal amount of phase change. Correction control data provided as the correction voltage data at each sampling time is applied to a transmission control section. The transmission control section generates transmission control data based on the correction control data and applies the transmission control data to a VCO through a DAC.
