Modified Monte-Carlo Technique for the Simulation of Satellite Communication Systems.

摘要

Civilian and military communication networks use satellite links for digital transmission of information. The analysis of performance of digital communication systems operation over non-linear satellite channels is a difficult task and no complete analytical treatment of the problem is currently available. Several recent efforts have been directed towards the evaluation of performance as measured by the end-to-end symbol error probability using Monte-Carlo simulations. These simulations require excessively large sample sizes and are not practical for estimating low values of error probabilities. In this report, the investigators present a technique for reducing the sample size requirements of Monte-Carlo simulation of satellite communication links. The method is based on a combination of a modified (importance) sampling technique and an extrapolation technique Sample size reduction of the order of 100 appears to be possible with this technique.
