ABSTRACT:
A method and circuit for adaptively determining a pilot signal reacquisition time. A searcher subsystem measures a phase of the pilot signal. A control processor measures a magnitude of a shift in the pilot signal phase, compares the measured magnitude to a shift threshold, and decreases the reacquisition time if the measured magnitude is not greater than the shift threshold. The control processor also may compare the reacquisition time to a minimum reacquisition time, and decrease the reacquisition time only if the reacquisition time is greater than the minimum reacquisition time. Additionally, the control processor may increase the reacquisition time to a maximum reacquisition time if the measured magnitude is greater than said shift threshold.
