Mathematical Modelling of Errors on a Satellite Channel: Theory and Practice.

Abstract

This report details a cooperative RL/AFOSR project to provide a laboratory environment for test and evaluation of equipments/protocols that are or will be used in DOD/Federal/Commercial networks utilizing disadvantaged' communications links with higher error rates than copper or fiber. One way is to utilize Error Injector Units (EIU) previously developed under another Rome Lab Effort: "Markov Models for Data Communications." The EIUs are inserted between communication networking equipments to emulate the errors seen over these links, giving the user an idea of actual equipment/protocol performance. Accurate, reliable, transition matrices must be generated for the Markov models used in the ElUs, based on bit error sequences collected by observing live, over-the-air channels during operation. The report focusses on identifying metrics to evaluate the fidelity of a suggested model and proposing methods of generating models which attempt to optimize one or more of these metrics. A procedure is outlined for the use of these models and metrics in a testing environment. (AN)
