Cet article présente les résultats sur la conversion numérique directe haut/bas IF/bande de base et les modules radio définis par logiciel d'analyse/synthèse à canaux multiples qui sont implémentés à l'aide d'ADC, DAC et FPGA haute vitesse, pour les systèmes à accès multiple par répartition en code (CDMA) IS-95. Le système mis en œuvre peut directement convertir des signaux IF CDMA IS-95 à plusieurs canaux en bande de base et analyser sélectivement des signaux de canal spécifiques sur la base de techniques de banc de filtres d'analyse polyphasée. De plus, les signaux en bande de base analysés de plusieurs canaux peuvent être directement convertis et synthétisés dans le même système. Nous avons déployé le système mis en œuvre dans des répéteurs numériques optiques CDMA IS-95 pour les applications PCS.

Abstract: This paper presents the results on IF/baseband up/down direct digital conversion and multiple channel analysis/synthesis software defined radio modules which are implemented using high speed ADC, DAC and FPGA, for IS-95 code division multiple access (CDMA) systems. The implemented system can directly down-convert multiple channel IS-95 CDMA IF signals to the baseband, and selectively analyze specific channel signals based on polyphase analysis filter bank techniques. Moreover, the analyzed baseband signals of multiple channels can be directly up-converted and synthesized in the same system. We have deployed the implemented system in IS-95 CDMA optical digital repeaters for PCS applications.
