NOTAS: | "Discusses the use of low Earth orbital (LEO) satellite systems for a global personal communication network (PCN), concentrating on the performance of LEO satellite systems with employment of either CDMA or spread-slotted Aloha, and on the problem of nonuniform distribution of traffic loads around the world. Presents analytical frameworks for evaluating the performance of LEO satellite systems, and introduces techniques for improving performance including methods modified from conventional power control and methods focusing on control of user transmissions. Other topics include packet admission control and multibeam LEO satellites." |
