Title
(EN) SYSTEMS AND TECHNIQUES FOR SPACE-TIME CODED COCHANNEL INTERFERENCE CANCELLATION
(FR) SYSTEMES ET TECHNIQUES POUR LA SUPPRESSION DES INTERFERENCES DES CO-CANAUX CODEE ESPACE-TEMPS
Abstract
(EN)
An apparatus, system, and method for space-time cochannel interference cancellation are described. The apparatus may include a time stacking module to stack consecutive subcarrier signals for a period of time equal to several symbols and a space-time subcarrier beamformer module to perform space-time subcarrier beamforming by applying space-time beamformer weights to stacked symbols on one or more subcarriers. The space-time beamformer weights may be calculated based on spatial and time correlation properties of one or more interference signals. Other embodiments are described and claimed.
(FR)
Appareil, système et procédé destinés à la suppression des interférences des co-canaux espace-temps. L'appareil peut comprendre un module d'empilage temporel, destiné à empiler les signaux consécutifs de sous-porteuses pour une période équivalant à plusieurs symboles et un module de formateur de faisceaux de sous-porteuses espace-temps destiné à effectuer une formation de faisceaux de sous-porteuses espace-temps par l'application des pondérations de formation de faisceaux espace-temps aux symboles dans une ou plusieurs sous-porteuses. Les pondérations de formation de faisceaux espace-temps peuvent être calculées sur la base des propriétés de corrélation spatiale et temporelle ou d'un ou plusieurs signaux d'interférence. L'invention porte également sur d'autres modes de réalisation.
