ABSTRACT:
A searcher is centered on frequency bins to search for an incoming signal. The frequency locked loop generates an initial phase signal and a phase increment signal that are input to an accumulator. The accumulator accumulates the phase increments over a predetermined interval. After the interval, the accumulator generates a control signal that instructs a rotator to perform a phase rotation function.
