Abstract
In this paper, a cluster satellite system is considered in which an ALOHA system is used to carry out power control and coding in the uplink and a time division multiple access system is used for the downlink and for intersatellite communication. First, the effects of the coding and the power control in the uplink are evaluated by using the error rate of the maximum level signal. Next, the network characteristics of this cluster satellite system are derived by computer simulation. It is shown that the improvement of the throughput and the coding delay is particularly significant at a low CNR. Further, the effect of the number of buffers on board the satellite on the entire system is evaluated. © 2000 Scripta Technica, Electron Comm Jpn Pt 3, 83(5): 76–82, 2000
