Abstract:
Disclosed methods of terrestrial station monitoring of downlink signal quality include receiving a sequence of samples of reference symbol slots of a downlink burst, and estimating a time offset between a local clock and a timing of a symbol pattern carried by the reference symbol slots, using a local copy of the reference symbol pattern. A corresponding time correction is applied to the sequence of samples to form time corrected samples of symbols carried by the reference symbol slots. A frequency offset between the time corrected samples of the symbols carried by the reference symbol slots and a local clock is estimated. A corresponding frequency compensation is applied to the time corrected samples, forming time/frequency compensated samples of the symbols carried by the reference symbol slots. A signal to noise plus interference ratio (SNIR) estimation data, and corresponding estimate of signal path, is generated, based on moments of the time/frequency compensated samples.

Claim (Index 9):
The system of  claim 1 , wherein the system further includes a tracking/acquisition management logic, wherein the tracking/acquisition management logic is configured as switchable among a tracking mode, a stop mode, and an acquisition mode, wherein:\n in the tracking mode the tracking/acquisition management logic is configured to:\n apply a tracking loop, the tracking loop including a generating, based at least in part on a recursive filtering of the estimated SNIR data, of a tracked SNIR data, and \n upon detecting an outage condition, to stop the tracking loop, the outage condition based at least in part on the tracked SNIR data, and switching to the stop mode; \n in the stop mode, the tracking/acquisition management logic is configured to switch to the acquisition mode upon receipt of an acquisition mode command; and in the acquisition mode, the tracking/acquisition management logic is configured to apply a burst detection process and, upon a burst detection by the burst detection process, to switch to the tracking mode.
