Abstract

La présente invention permet l'amélioration de la performance de systèmes de traitement de réseau d'antennes adaptatif. En particulier, la présente invention concerne l'optimisation de réception et de transmission de signaux qui utilisent un codage convolutionnel et des décodeurs de Viterbi. La présente invention utilise une certaine information dérivée de décodeurs de Viterbi pour améliorer la performance d'un algorithme génétique dans l'optimisation de la réception et de la transmission de signaux dans un système de réseau d'antennes adaptatif.
