ABSTRACT:
A method and a device adapted to hands-free mobile radiotelephony for the optimized processing of a disturbing signal during a sound capture, on the basis of an observation signal y(t) formed of an original useful signal s(t) and of this disturbing signal p(t), the disturbing signal is estimated as a signal p(t) and the useful signal as an estimated useful signal su. An optimal filtering of the observation signal y(t) is carried out on the basis of the signal p(t) and of a minimizing 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 converge towards the original useful signal s(t) for a substantially zero error e(su,su).
