Abstract :
The problem of deconvolution of a signal distorted by a linear time-invariant system is considered. In order to regularise this ill-posed problem; we combined the use of optimal filter, the game theory approach applied to the tracking problem and the priori knowledge such as positivity on the restored signal. To illustrate the robustness of the exposed procedure, two numerical examples are given
