Multiservice Traffic Model and Bandwidth Demand for Broadband Satellite Systems

摘要

This paper outlines a methodology to estimate the (information) capacity requirements and the corresponding bandwidth demand for a multi-spotbeam multiservice satellite system. The two basic components of the methodology are (i) an analytical estimation of single-service bandwidth demand for both FDM/TDMA and FDM/CDMA satellite systems, and (ii) a general and tractable approach to system capacity dimensioning, essentially based on a new generic multiservice source traffic model. One of the key features of the multiservice model is its scalability, making it a practicable and future-proof tool in the rapidly evolving broadband communications world. Finally, a numerical evaluation of capacity and bandwidth requirements for a specified study system is provided.
