Baseband switches and transmultiplexers for use in an on-board processing mobile/business satellite system

The paper reviews the traffic requirements for two specific services which will benefit by the use of on-board processing: (i) business satellites for European coverage and (ii) land mobile satellites for Europe. Although the traffic requirements are very different for the two services, the proposed architectures are similar in comprising a mixture of baseband switches and transmultiplexers. The paper reviews various architectures for both components, and estimates the chip count and power requirements for the various architectures.
