Factors involved in determining the performance of digital satellite links

The paper starts with a summary of the techniques available for implementing digital satellite transmission systems, then goes on to discuss current and probable new error performance objectives that will be consistent with the requirements of the Integrated Services Digital Network (ISDN). The main body of the paper discusses factors which affect performance, including capacity/quality trade-offs, satellite and Earth station parameters, atmospheric propagation conditions, interference and intermodulation. The conclusion indicates briefly the techniques available to a system designer to meet performance requirements.
