Raina Modak Aich, Supriya Dhabal, P. Venkateswaran · 2022
This paper proposes an improved Differential Evolution based Sine Cosine Algorithm (DESCA), to design a Near-Perfect Reconstruction (NPR) Quadrature Mirror Filter (QMF) bank. The proposed population-based DESCA algorithm is used here to optimize the Finite Impulse Response (FIR) filter coefficients that function as the prototype filter of the QMF filter bank. The proposed DESCA algorithm is compared with latest state-of-the-art algorithms which ensure the effectiveness of the proposed algorithm. Field Programmable Gate Array (FPGA) implementation is done for the proposed DESCA algorithm for different filter taps and simulated with Xilinx ISE Design Suite. The performance result of the proposed DESCA algorithm demonstrates its ability in solving complex multimodal problems with respect to the existing state-of-the-art algorithms.
