Abstract
This paper proposes a novel method which is based on particle swarm optimization (PSO) algorithm for the two-dimensional FIR digital filter design. In the PSO algorithm, it simply uses two adjusting mechanisms including particle’s velocity and position updating to achieve the optimization. In addition, numerical representations for each candidate solution are completely real numbers. The PSO algorithm is utilized to design the two-dimensional FIR digital filter with linear-phase characteristic so that its frequency response can approximately meet the desired specification. Finally, we will illustrate the design performance of the proposed method with two experiments. Simulation results reveal that the proposed scheme has a good design performance on the two-dimensional FIR digital filter.
