Demand-assignment schemes for SCPC FDMA satellite systems with contiguous spot beams

Attention is given to the grade of service, traffic capacity, frequency allocation and possible number of channels for contiguous multibeam operation under various demand-assignment schemes. Fixed-, dynamic-, and mixed-assignment schemes are treated, with and without frequency reuse. Simple examples are presented to highlight the particular features of these schemes, and analytical expressions for their performance are deduced where appropriate. The treatment is broadened to include practical systems, such as the proposed North American mobile satellite and the Australian domestic satellite systems.
