Optimization of the reconstruction and anti-aliasing filter in a wiener filter system
conference paper
This paper discusses the influence of the reconstruction and anti-aliasing filters on the performance of a digital implementation of a Wiener filter for active noise control. The overall impact will be studied in combination with a multi-rate system approach. A reconstruction and anti-aliasing filter will be selected and its parameters will be varied to optimize the system level performance of the Wiener filter for a feedback controller based on an internal model control principle. It will be shown that the selection of the reconstruction and anti-aliasing filter is an important decision that can largely influence the overall system performance. This method can be used in combination with standard optimization algorithms to automatically find the optimal filters that will give the largest reduction for the overall system.
