An adaptive modulation scheme for low Earth orbit satellites

LEO satellites present widely varying signal conditions. Fixed modulation schemes are designed for the worst operating conditions and cannot take advantage of the better signal to noise conditions present at high elevations. An adaptive modulation scheme, which uses different constellation patterns...
