Abstract: A signal receiver may be configured to determine when signal generation adjustments directed to particular components of signals received by the signal receiver, cause performance changes relating to effects of the signal generation adjustments on other components of the received signals. Operations of the signal receiver may then be controlled based on the performance changes, to mitigate at least some of the effects on the one or more other components of the signals. The performance changes may comprise amplitude glitches, phase glitches, and/or bit or packet errors. The signal generation adjustments may comprise channel-to-frequency re-assignment. Controlling operations of the signal receiver may comprise adjusting such parameters as amplification gain and/or tracking loop bandwidth, and/or determining whether (or not) to ignore bit/packet errors.

Abstract: Methods and systems are provided for using priori knowledge of noise in controlling signal receivers. In a signal receiver, one or more adjustments, relating to generating output signals via the signal receiver, may be determined, with the adjustments directed to one or more particular components of the output signals. When applying the adjustments is determined to cause undesired effects on one or more other components of the output signals, with these other components being intended to remain unchanged when the adjustments are applied, operations of the signal receiver may be controlled based on the undesired effects, with the controlling including mitigating at least some of the effects on the one or more other components of the signals when the one or more adjustments are applied. The adjustments may include frequency re-assignment. The undesired effects may include one or more of amplitude glitches, phase glitches, bit or packet errors, etc.

Abstract: A signal receiver may be configured to determine when signal generation changes affecting signals being received by the signal receiver may cause performance related changes; and to modify its (the signal receiver) configuration to handle the performance related changes. In this regard, the modifying of configuration may comprise determining characteristics of performance related changes, and controlling operations of the signal receiver based on the determined characteristics of the performance related changes. The performance related changes may comprise amplitude glitches, phase glitches, and/or bit or packet errors. The signal generation changes may comprise channel-to-frequency reassignment. Controlling operations of the signal receiver based on determined characteristics of the performance related changes may comprise adjusting such parameters as amplification gain and/or tracking loop bandwidth, and/or determining whether (or not) to ignore bit/packet errors—i.e. not reacquire (e.g., based on determination that tracking loops used in the signal receiver remain locked).
