Abstract

In this paper we propose first a generalized framework for the Maximum Likelihood decoding ofstbc. Using algebraic tools we then derive a new matrix model particularly well suited to the description ofmimo systems. After giving our particular detection rules we determine a new accurate upperbound for theber performances ofstbc transmitting schemes. Performance results are given which show the accuracy of the derived upperbound.

Résumé

Ce papier aborde le problème du décodage des codes temps-espace en blocs, les règles de décodage sont rappelées et une formulation matricielle particulièrement simple est obtenue pour une programmation rapide. Cette modélisation matricielle nous permet d’obtenir un calcul de borne supérieure duteb sur canal de Rayleigh non sélectif en fréquence. Les performances obtenues sont excellentes et montrent la précision des bornes obtenues.
