Abstract:
(EN) Provided are a continuous updating method and device for a finite impulse response filter coefficient vector. A continuous self-adaptive updating method for a finite impulse response (FIR) filter coefficient vector comprises: acquiring a time-varying regularization factor for FIR filter coefficient vector iterative updating when a pre-set signal is processed by using an FIR filter coefficient vector (21); and according to the time-varying regularization factor, updating the FIR filter coefficient vector (22).
(FR) La présente invention concerne un procédé et un dispositif de mise à jour continue pour un vecteur de coefficient de filtre à réponse impulsionnelle finie. Un procédé de mise à jour auto-adaptative continue pour un vecteur de coefficient de filtre à réponse impulsionnelle finie (RIF) comprend : l’acquisition d’un facteur de régulation variable dans le temps pour une mise à jour itérative du vecteur de coefficient de filtre à RIF lorsqu’un signal prédéfini est traité à l’aide d’un vecteur de coefficient de filtre à RIF (21) ; et selon le facteur de régulation variable dans le temps, la mise à jour du vecteur de coefficient de filtre à RIF (22).
