Abstract (en)

[origin: EP0884926A1] 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.
