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 within a communications receiver. The filter 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). 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.
L'invention porte sur un dispositif de communication sans fil qui peut comprendre un émetteur sans fil et un récepteur sans fil.L'émetteur sans fil peut comprendre un filtre destiné à réduire l'interférence entre canaux à l'intérieur d'un récepteur de communications. Le filtre peut comprendre un circuit de filtrage spatio-temporel multicanal qui filtre n parties de signal qui ont été séparées d'un signal de communication, en estimant de manière conjointe les pondérations de filtrage spatio-temporel et les réponses impulsionnelles multicanal ("multi-channel impulse responses" ou CIR). Le filtre précité peut en outre comprendre un circuit de filtrage multicanal accordé qui reçoit des signaux multicanal en provenance du circuit de filtrage spatio-temporel multicanal et qui fournit une réponse de filtrage basée sur une estimation de la réponses impulsionnelle de canal en provenance du circuit de filtrage spatio-temporel.
