Title (EN) WIRELESS COMMUNICATIONS DEVICE INCLUDING A JOINT SPACE-TIME OPTIMUM FILTERS (JSTOF) USING QR AND EIGENVALUE DECOMPOSITIONS
(FR) DISPOSITIF DE COMMUNICATION SANS FIL COMPRENANT DES FILTRES OPTIMAUX ESPACE-TEMPS COMBINES (JSTOF) UTILISANT UNE DECOMPOSITION QR ET UNE DECOMPOSITION EN VALEURS PROPRES
Abstract: front page image
(EN)A wireless communications device may include a wireless transmitter and a wireless receiver. The wireless receiver may include a filter for reducing co-channel interference and may include a multi-channel, space-time filter circuit that filters n signal parts that have been split from a communications signal by jointly estimating space-time filter weights and multi-channel impulse responses (CIRs) based upon QR and eigenvalue decompositions. The filter may further include a multi-channel, matched filter circuit that receives multi-channel signals from the multi-channel, space-time filter circuit and has a filter response that is provided by a channel impulse response estimation from the space-time filter circuit.
(FR)L'invention concerne un dispositif de communication sans fil qui peut comprendre un émetteur sans fil et un récepteur sans fil. Le récepteur sans fil peut comprendre un filtre permettant de réduire le brouillage dans un même canal, et un circuit filtrant espace-temps multicanal qui filtre n parties de signal obtenues par division d'un signal de transmission, en estimant conjointement les coefficients de pondération espace-temps et les réponses impulsionnelles multicanal (CIR) à partir d'une décomposition QR et d'une décomposition en valeurs propres. Le filtre peut en outre comprendre un circuit filtrant adapté multicanal qui reçoit les signaux multicanal en provenance du circuit filtrant espace-temps multicanal, et dont la réponse résulte d'une estimation de la réponse impulsionnelle du canal du circuit filtrant espace-temps.
