L'interférence d'accès multiple (MAI) due au grand nombre d'utilisateurs simultanés est le principal facteur limitant les performances du système DS-CDMA. La détection multi-utilisateurs est une méthode permettant d’éviter la dégradation des performances due au MAI. Nous proposons une méthode de détection multi-utilisateurs aveugle basée sur un algorithme consistant en un processus de décodage en deux étapes, à savoir un module constant contraint linéairement (LCCM) et des moindres carrés itératifs (ILS). Les simulations informatiques ont confirmé que l'algorithme est résistant de près et de loin et que la méthode proposée est efficace dans l'application aux canaux à évanouissement lent.

Abstract: Multiple access interference (MAI) due to many simultaneous users is the main factor that limits the performance of DS-CDMA system. Multiuser detection is a method to avoid performance degradation due to MAI. We propose a blind multiuser detection method based on the algorithm consisting of two-stage decoding process, i.e., linearly constrained constant modulus (LCCM) and iterative least squares (ILS). The computer simulations confirmed that the algorithm is near-far resistant and that the proposed method is effective in the application to the slow fading channels.
