A filter for reducing co-channel interference within a communications receiver 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 concerne un filtre permettant de réduire le brouillage dans le même canal à l'intérieur d'un récepteur de communications, qui peut comprendre un circuit filtrant spatio-temporel multicanaux qui filtre n parties de signal ayant été séparées d'un signal de communications par estimation conjointe de pondérations du filtre spatio-temporel et de réponses impulsionnelles multicanaux (CIR). Ledit filtre peut également comprendre un circuit filtrant adapté multicanaux qui reçoit des signaux multicanaux du circuit filtrant spatio-temporel multicanaux et qui présente une réponse de filtre produite par une estimation de réponse impulsionnelle de canal provenant du circuit filtrant spatio-temporel.
