ABSTRACT:
A method for compensating for power variations in satellite communications includes measuring or estimating power variations for signals received at an earth-based terminal. The method also includes measuring or estimating changes in carrier-to-noise levels by a number of satellite terminals. The power variations may then be used to adjust the measured/estimated changes in carrier-to-noise (C/N) levels. The adjusted C/N levels may then be used to more accurately reflect actual network conditions and may be used in downlink power control related processing.
