Title
(EN) METHOD AND ARRANGEMENT IN A COMMUNICATION SYSTEM
(FR) PROCEDE ET AGENCEMENT D'UN SYSTEME DE COMMUNICATION
Abstract
(EN)
The present invention relates to a method, a device and a software product at a mobile telecommunication and data communication system according to the introduction to the independent patent claims. More exactly the method relates to make measurings in real time possible of the in said system specified measuring quantity Signal-to-Interference Ratio (SIR), where SIR is adapted to the mobile telecommunication and data communication system Code Division Multiple Access (CDMA). The aim of the present invention is to effect a way to estimate SIR in real time when SIR is adapted to CDMA. This is achieved by the algorithm according to the invention operating directly on the scrambling sequence instead of specific training sequences.
(FR)
L'invention concerne un procédé, un dispositif et un produit logiciel dans un système mobile de télécommunications et de communication de données. Plus précisément, le procédé vise à rendre possible des mesurages en temps réel du rapport signal/interférence (SIR) de la valeur de mesure spécifiée dans ledit système, ce rapport étant adapté à l'accès multiple par code de répartition (AMCR) du système mobile de télécommunications et de communication de données. L'invention concerne une manière d'estimer le rapport SIR en temps réel lorsque ce rapport est adapté à l'AMCR, ce que l'on réalise conformément à l'invention, par l'algorithme fonctionnant directement sur la séquence de brouillage plutôt que sur des séquences d'apprentissage.
