System and Method for Frequency Pushing/Pulling Compensation

摘要

A system and method for frequency pushing/pulling compensation in phase-locked loops including a method for cancelling frequency push/pull in an oscillator of a transmitter. The method includes computing an error signal from a signal of a phase locked loop, wherein the error signal includes an aggressor signal. Transfer characteristics are computed for the aggressor signal. A transmitted signal is filtered using the transfer characteristics to produce a correction term. The correction term is applied to a frequency control word being provided to the oscillator.
