A moment generating function (MGF)-based approach for performance evaluation of space-time coded communication systems

摘要

A few years back, a generic analysis approach referred to as the MOF method was introduced for the purpose of simplifying the evaluation of the performance of digital communication over fading channels. A particular case of high interest that fell under the umbrella of the methodology was the evaluation of the average error probability performance of Systems that employ receive diversity to combat multipath as well as the possible inclusion of error-correcting coding/decoding for improving power efficiency. In this paper, we extend the methodology to space-time coded systems. Illustrative examples are explicitly given for space-time trellis coding. The emphasis of the paper is on the performance analysis tools and their application, as opposed to the design of the space-time codes themselves.
