A digital communications system and method to transmit and receive a digital communications signal wherein the digital signal has a plurality of frames, wherein at least two modulations are supported, and wherein each of the plurality of frames has the same number of symbols.

Efficient frame structure for digital satellite communication

An uplink power control system for terminals in a satellite communication system provides closed loop power control using feedback signals generated at a satellite. The satellite performs inter-beam routing of uplink signals from satellite terminals, and processing of uplink signals to generate terminal transmission-specific feedback information that is transmitted in downlink signals to the terminals. The satellite also generates a beacon signal. An uplink power control algorithm at each terminal uses the beacon signal and feedback data to adjust transmit power.
