Multiple access techniques for low data rate satellite communication systems
Abstract
There are many applications of low data rate satellite communications that range from data collection to position surveillance. A common characteristic of all of these systems is that a low cost design is essential and the maximum throughput should be achieved. In this paper we discuss a set of multiple access techniques that can be employed for such applications. We provide a detailed analysis of a broad set of possibilities for a digital multiple access scheme ranging from a pure random access scheme to a pure spread spectrum. Specific implementation problems are also addressed and the techniques proposed in a data collection system are discussed.
