An Improved Method for Designing MTD Filter Coefficients Based on Second-Order Cone Programming

To improve the convergence performance of filter coefficient solving processes, align the filter frequency response curve more closely with the desired frequency response curve, and enhance the robustness of the filter coefficient solving method, this paper proposes an improved MTD filter coefficient solving method based on second-order cone programming. This method can achieve a filter frequency response that closely aligns with the desired frequency response. The effectiveness of the method is verified through simulation experiments and actual measured data.
