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 1):
A system for estimating a received signal quality, comprising:\n a memory, configured to store a reference symbol pattern; a first processing engine, configured to:\n receive a sampling sequence, corresponding to a sampling of reference symbol slots of a received signal burst, \n estimate a time offset between a local clock and a timing of symbols carried by the reference symbol slots, based at least in part on the stored reference symbol pattern and the sampling sequence, and \n time correct the sampling sequence to form a time corrected sample sequence of symbols carried by the reference symbol slots, based at least in part on the estimated time offset; \n a second processing engine, coupled to the memory and to the first processing engine, and configured to:\n estimate a frequency offset between the symbols carried by the reference symbol slots and a local clock, based at least in part on the stored reference symbol pattern and the time corrected sample sequence, and \n frequency compensate the time corrected sample sequence, to generate a frequency/time compensated sample sequence, based at least in part on the time corrected sample sequence and the stored reference symbol pattern; and \n a third processing engine, configured to generate a signal to noise plus interference ratio (SNIR) data, based at least in part on a statistical moment of the frequency/time compensated sample sequence and, based at least in part on the SNIR data, generate an estimated received signal quality data.
