Nous étudions la compensation de dispersion à l'aide de fibres à compensation de dispersion (DCF) pour les systèmes de communication à accès multiple par répartition en code d'impulsions lumineuses ultracourtes (CDMA) dans un environnement multi-utilisateurs. Nous utilisons une liaison fibre qui consiste en une fibre monomode standard (SMF) connectée à deux types différents de DCF. La dispersion des fibres peut être efficacement réduite en ajustant les rapports de longueur des DCF par rapport aux SMF de manière appropriée. Certains critères de compensation de dispersion sont proposés et leurs performances sont comparées. Nous dérivons théoriquement un taux d'erreur sur les bits (BER) des systèmes CDMA à impulsions lumineuses ultracourtes, incluant les effets de la dispersion et des interférences d'accès multiple (MAI). De plus, nous révélons pour la première fois les relations mutuelles entre les performances du BER, la dispersion des fibres, le MAI, le nombre de puces, la bande passante d'un signal et la distance de transmission. En conséquence, nous montrons que notre stratégie de rémunération améliore considérablement les performances du système.

Abstract: We investigate dispersion compensation using dispersion-compensating fibers (DCFs) for ultrashort light pulse code division multiple access (CDMA) communication systems in a multi-user environment. We employ fiber link that consists of a standard single-mode fiber (SMF) connected with two different types of DCFs. Fiber dispersion can be effectively decreased by adjusting the length ratios of DCFs to SMF appropriately. Some criteria for dispersion compensation are proposed and their performances are compared. We theoretically derive a bit error rate (BER) of ultrashort light pulse CDMA systems including the effects of the dispersion and multiple access interference (MAI). Moreover, we reveal the mutual relations among BER performance, fiber dispersion, MAI, the number of chips, a bandwidth of a signal, and a transmission distance for the first time. As a result, we show that our compensation strategy improves system performance drastically.
