Signal Design Decision-Making and Efficient Use of Geostationary Satellite Orbit/Spectrum

摘要

Based on the concept of general interference isolation, this paper deals with the signal decision-making of the combined operation of various modulation schemes in satellite networks and the efficient use of geostationary satellite orbit/spectrum. The signal design is aimed at general high efficient modulation schemes including coded modulations, modified-constellation QAM schemes and ACSB, etc.The methodology presented here will be helpful for coordination estimation, allocation of frequency spectrum and orbit spacing, and performance prediction and design of any type inhomogeneous satellite systems and/or networks.
