Detection and compensation of dielectric resonator oscillator frequency drift

摘要

Systems and methods are provided for detection and compensation of dielectric resonator oscillator frequency drift. DRO frequency drift detection and compensation may be applied in a system (e.g., outdoor unit) during handling of received signals. The DRO frequency drift detection and compensation may comprise, for each input signal, obtaining DRO frequency drift related information, related to the input signal; determining, based on the obtained DRO frequency drift related information, one or more adjustments applicable to processing of the input signal and/or the generation of the output signal using the at least portion of the input signal; and applying the one or more adjustments. The DRO frequency drift detection and compensation may be applied continually, occasionally, and/or periodically.
