Abstract

PURPOSE: To quicken the FH by restricting the adaptive control at FH synchronization and setting the initial value of the adaptive control to a required value.
CONSTITUTION: A signal outputted from an adder 6 is demodulated by a detection circuit 11 and noise is eliminated by a base band filter 12 and the output of the base band filter 12 is detected as to whether it is in the synchronizing state or not at that time by a synchronizing detection circuit 13 and the condition of a control condition set switch 17 is set. A weight control circuit 10 designates the restriction of the adaptive control in the synchronization acquisition state and the execution of control in the synchronizing state depending on the setting condition of the control condition setting switch 17. Moreover, an initial condition storage circuit 18, based on the hopping timing from a frequency synthesis section 16, stores the weight control converging data at the preceding hopping and gives it to the weight control circuit 10 as the weight initial data for the adaptive control at the next hopping. Thus, the adaptive control converging time is quickened.
