Abstract :
Among other applications, frequency-tracking loops are employed in digital-data receivers, either as a frequency-acquisition aid for phase-locked coherent reception, or as the sole carrier-frequency control for noncoherent reception. This article provides details of design and performance of the frequency-difference detector that lies at the heart of the loop.
