Dans cet article, les impacts de l'utilisation de plusieurs antennes d'émission sous des canaux MIMO doublement corrélés sur l'acquisition de code de liaison montante CDMA sont étudiés. Les performances d'un système d'acquisition de code MIMO sont analysées en considérant les corrélations d'évanouissement spatial, qui dépendent de l'espacement des antennes et de la propagation en azimut au niveau de la MS et de la BS. Les performances de détection et le temps d'acquisition moyen en présence d'un canal MIMO spatialement corrélé sont présentés sur un canal à évanouissement sélectif en fréquence et comparés aux cas de décorrélation à évanouissement spatial via une évaluation numérique. On observe que les performances d’acquisition dépendent du degré de corrélation des évanouissements spatiaux. De plus, il est surprenant de constater qu’un système d’acquisition de code MIMO offre de moins bonnes performances que SIMO.

Abstract: In this paper, the impacts of using multiple transmit antennas under doubly correlated MIMO channels on CDMA uplink code acquisition is studied. The performance of a MIMO code acquisition system is analyzed by considering spatial fading correlations, which depend on antenna spacing and azimuth spread at both MS and BS. The detection performance and mean acquisition time in the presence of spatially correlated MIMO channel are presented on a frequency selective fading channel and compared with the cases of spatial fading decorrelation via numerical evaluation. It is observed that the acquisition performance relies on the degree of spatial fading correlations. In addition, it is surprisingly seen that a MIMO code acquisition system provides worse performance than SIMO.
