Abstract
(EN)
A method and equipment for realizing smart antenna in WCDMA system are disclosed, the equipment comprises array antenna, RF channel module, beam-forming module, channel environment detection and classification module, beam-forming algorithm selection and weights generation module. After processing the signals received by the antenna in RF channels, the base-band array data X which contains multi-components is obtained, estimating and identifying the channel environment according to the features of said array data, and determining current channel type of the channel; selecting corresponding adaptive beam-forming algorithm immediately based on the identification result of the channel type, so as to calculate up-link weights W containing multi-components; multiplying said array data X and weights W so as to form the beam Y. The invention could employ corresponding adaptive beam-forming algorithm based on the channel environments, thus could restrain interference effectively under various channel environments.

L’équipement comprend une antenne réseau, un module de canal RF, un module de formation de faisceau, un module de détection et de classement d’environnement de canal, une sélection d’algorithme de formation de faisceau et un module de génération de pondérations. Après le traitement des signaux reçus par l’antenne dans les canaux RF, les données de tableau de bande de base X contenant des multicomposants sont obtenues, l’environnement de canal est estimé et identifié selon les caractéristiques desdites données de tableau et le type actuel du canal est déterminé ; l’algorithme adaptatif correspondant de formation de faisceau est sélectionné à partir directement du résultat d’identification du type de canal, de façon à calculer les pondérations de liaison amont W contenant des multicomposants ; lesdites données de tableau X et des pondérations W sont multipliées de façon à former le faisceau Y. L’invention permet d’employer un algorithme adaptatif correspondant de formation de faisceau basé sur l’environnement de canal, réduisant ainsi de manière efficace les interférences dans des environnements de canal différents.
