摘要

The present invention relates to a communication system and method that allows a transmitter segment (ground end of uplink segment) to dynamically combine power from plurality of propagation channels (transponders) in order to improve power levels of signals being transmitted, without affecting the receiver segment (user end of downlink segment) and the propagation segment (space segment), and without modifying the configuration of the propagation apparatus (satellite). Specifically, the transmitter segment generates mixtures of input signals by using Wavefront-Multiplexing and transmits the wavefront-multiplexed (WFM) signals through propagation channels to a receiver segment that coherently separates the mixtures of received WFM signals by using adaptive equalization and Wavefront-De-Multiplexing. The WFM signal mixtures allow an operator, or automated system, at the transmitter segment to dynamically allocate equivalent channel (transponder) powers according to continuously changing market demands by dynamically including change of relative input powers into ratios of the WFM signal mixtures being transmitted.
