Cet article propose un nouveau modem à spectre étalé (SS) pour les systèmes de communication par satellite à accès aléatoire qui utilise des filtres numériques adaptés. Le modem proposé utilise une structure parallèle pour assurer la détection de l'arrivée des paquets. La détection de synchronisation de code avec une combinaison d'un détecteur grossier et d'un détecteur d'erreur fractionnaire réduit le taux d'échantillonnage tout en maintenant les performances BER. Un schéma de multiplexage pilote en symbole est également proposé pour une synchronisation rapide et stable des porteuses avec un matériel simple. Une évaluation des performances montre que le modem proposé atteint la probabilité de détection d'échec UW de 10.-4 au Eb/No de 0 dB. Les performances globales du BER obtenues lors des expériences concordent bien avec la simulation.

Abstract: This paper proposes a novel spread spectrum (SS) modem for random access satellite communication systems that employs digital matched filters. The proposed modem employs a parallel structure to ensure detection of packet arrival. Code timing detection with a combination of a coarse detector and a fractional error detector reduces the sampling rate while maintaining the BER performance. An in-symbol pilot multiplexing scheme is also proposed for fast and stable carrier synchronization with a simple hardware. A performance evaluation shows that the proposed modem achieves the UW miss-detection probability of 10-4 at the Eb/No of 0 dB. The overall BER performance achieved in experiments well agrees simulation.
