Abstract
In various implementations, a re-configurable phase lock loop may have multiple signal paths, including a feedforward path to operate in a carrier frequency acquisition mode to obtain a carrier frequency estimate and a feedback loop path to operate in a carrier frequency tracking mode to translate an incoming signal to a baseband signal. The multiple signal paths may share most of the hardware to reduce implementation cost.
