Abstract(in English) An analytical framework to study the nonuniformity in geographical distribution of the traffic load in low earth-orbital satellite communication systems is presented.Throughput characteristics of the system with direct-sequence packet spread- slotted ALOHA multiple-access technique are evaluated and it is shown that nonuniformity in traffic makes the characteristics of the system significantly different from the results of the uniform traffic case and that the performance of each user varies according to its location.Moreover,the interference reached from the users of adjacent satellites is shown to be one of the main factors that limits the performance of system.A scheme which changes the ratio of the required transmitting powers to the satellites,is also purposed and is shown that withthis method we can improve the throughput performance in dense traffic areas to some degrees.
