Abstract
A method and system for providing adaptive coded modulation in LEO satellite communication system is provided. The received power signal at the receiver is predicted by the LEO satellite transmitter without using channel feedback from the receiver. The receiver rapidly detects changes in transmission rate and changes its demodulation rate in tandem with the LEO satellite. Certain conditions that vary slowly, such as local weather and ground moisture level, are provided to the transmitter from the receiver at a much slower rate than that used in normal data communications.
