Outline of Final Research Achievements

We have theoretically analyzed the behaviors of adaptive signal processing based on statistical-mechanical method. Especially, we have analyzed the active noise control that is a technique to remove acoustic noise by sound. Some models have been analyzed that include the time-varying primary path, the actual primary path, the effect of the estimation error of the secondary path, the steady-state squared error, the upper bound of step size, multi-channel active noise control, and so on.
