Abstract: In CDMA communications, a base station detects a difference between a reference phase of a spreading code and a phase of a received signal of each terminal station, and feeds a phase jump signal PJ-i representative of the phase difference back to each terminal station. After timing acquisition, the reception operation is performed using the reference phase, and a shift amount between the phase of a received signal and the reference phase is fed back to each terminal station as phase synchronization control information PC-i. Each terminal station coarsely adjusts the phase of the spreading code in accordance with the phase jump signal PJ-i, and thereafter finely adjusts the phase of its transmitting signal in accordance with the phase synchronization control information PC-i. It is therefore possible to synchronize the phases of the signals transmitted from terminal stations and received at the base station. Accordingly, an orthogonal code is used for spreading on the reverse links.

Abstract: A signal from an original oscillation circuit is inputted into a phase-locked loop circuit capable of continuously varying a frequency of this signal derived from the original oscillation circuit. The phase-locked loop circuit changes the frequency of the signal derived from the original oscillation circuit into another frequency corresponding to sweep rate variable information derived from a sampling control unit, and then outputs the signal having the changed frequency. This signal outputted from the phase-locked loop circuit is supplied to a variable frequency dividing circuit. This variable frequency dividing circuit frequency-divides the frequency of the signal outputted from the phase-locked loop circuit at an arbitrary frequency dividing ratio corresponding to the sweep rate range information given from the sampling control unit, and thereafter outputs the signal with the frequency-divided frequency as a sampling signal.
