Title:
音響獲得の間における外乱信号の最適化された処理のための方法および装置
Document Type and Number:
Japanese Patent JP4409642
Kind Code:
B2
Abstract:
The method involves a series of iterative processing steps. An estimation (101) is made of the noise perturbation, and of the observed signal (102). An optimal filter (103) is used to produce a minimum error between the useful signal and the estimated useful signal. The error (104) between the two signals is optimised to a null value.
