L'invention concerne un récepteur spatio-temporel (ST) pour la suppression des interférences à accès multiple (MAI) et des interférences à bande étroite (NBI), ainsi que pour la réception en diversité à trajets multiples dans des communications CDMA multiporteuses sans fil incorporant des réseaux d'antennes. Le projet comporte trois étapes. Tout d’abord, un filtre adapté adaptatif est fixé à chaque doigt de chaque antenne pour lutter contre le MAI. Deuxièmement, un formateur de faisceau adaptatif est construit pour chaque doigt, ce qui permet une réception efficace du signal d'intérêt (SOI) et une suppression du NBI variable dans le temps. Enfin, les données de sortie du formateur de faisceaux provenant de différents doigts sont combinées pour capturer les composants du signal à trajets multiples de manière cohérente. Il est démontré que le récepteur ST proposé fonctionne de manière fiable sous de fortes interférences et surpasse le récepteur ST MMSE grâce à l'estimation de canal assistée par des symboles pilotes.

Abstract: A space-time (ST) receiver is proposed for multiple access interference (MAI) and narrowband interference (NBI) suppression, and multipath diversity reception in wireless multi-carrier CDMA communications incorporating antenna arrays. The scheme involves three stages. First, an adaptive matched filter is attached to each finger at each antenna to combat the MAI. Second, an adaptive beamformer is constructed for each finger which provides effective reception of the signal of interest (SOI) and suppression of time-varying NBI. Finally, beamformer output data from different fingers are combined to capture the signal multipath components coherently. The proposed ST receiver is shown to perform reliably under strong interference, and outperform the ST MMSE receiver with pilot symbols aided channel estimation.
