Method and device for processing the optimization of a disturbing signal during its

摘要

The invention relates to a method and device for the optimized processing of a disturbing signal during a sound capture, on the basis of an observation signal y (t) is formed of an original useful signal s (t) and of the disturbing signal p (t). the disturbing signal is estimated (101) by a signal p (t) and the useful signal (102) with an estimated useful signal su. An optimal filtering (103) of the observation signal y (t) is carried out on the basis of the signal p (t) and a minimization (104) of the error e (su, su) between the useful signal su and the estimated useful signal su. The estimated useful signal su and the useful signal converges towards the original useful signal s (t) to an error e (su, su) substantially zero. Application of the hands-free mobile telephony.
