The invention relates to a distributive intelligent antenna system which includes an antenna array with N antenna elements, N radio frequency transceivers and cables between them for connection. Firstly, N antenna elements and N radio frequency transceivers should be divided into groups according to cell coverage, then individual group of antenna elements should be distributed to different place within area covered by base station of same radio communication system based on coverage requirement, involving different buildings or different floors in same building, but all groups should share one baseband digital signal processor, 1 to M antenna elements can be configured in each group of antenna elements. It would develop advantage of intelligent antenna and improve cell coverage while increasing system capability and reducing cost.

L'invention concerne un système à antenne directionnelle intelligente distribuée comprenant des série d'antennes formées de N unités d'antennes, N émetteurs-récepteurs radioélectriques et des câbles de connexion. Les N unités d'antenne et les N émetteurs-récepteurs sont répartis en petits groupes de couverture selon la charge privée, puis chaque groupe d'unité d'antenne est réparti selon les besoins de couverture sur différents emplacements dans une zone de couverture ayant une station de base pour communication mobile. Ce système comprend en outre une pluralité de constructions et des étages différents dans les mêmes constructions ainsi que des processeurs de signaux numériques bande de base communs identiques. Chaque groupe d'unités d'antenne peut recevoir entre 1 et M unités. L'invention permet de développer l'antenne intelligente, d'améliorer la couverture tout en augmentant la performance du système et en réduisant le coût.
