Claim:
1. In a system receiving a composite signal comprising a desired signal having a desired frame including desired synchronization data and an interference signal, a method of receiving the desired signal and rejecting the interference signal, comprising the steps of: demodulating the composite signal; acquiring a phase of the desired synchronization data of the demodulated composite signal; tracking the acquired phase of the demodulated composite signal according to phase tracking information; sensing if the tracked phase of the demodulated composite signal is being drawn away from the desired signal by the interference signal; and choosing whether to update the phase tracking information according to whether the tracked phase of the demodulated composite signal is sensed to be being drawn away from the desired signal by the interference signal; wherein the sensing if the tracked phase of the demodulated composite signal is being drawn away from the desired signal by the interference signal is performed according to a statistical model of an expected phase of the desired synchronization data.
