Fast Two-dimensional WLS Techniques for the Design of Two-dimensioinal FIR Filters
This paper focuses on the design of two-dimensional (2-D) quadrantally symmetric.nite impulse response (FIR).lters, and presents three very ef.cient algorithms for the weighted least squares design with a weight matrix that assigns four different weights to four different frequency bands. The.rst algorithm seeks for iterative solutions to the matrix equation describing the optimality condition of the design problem. The second algorithm aims at the limit solution of the solution sequence of the.rst algorithm, analytically obtained by using matrix diagonalization techniques. The third algorithm belongs to the category of iterative reweighting technique. It uses the second algorithm as its iteration core, and aims at reducing the maximum magnitude error of the.lter by iteratively adjusting the four entry values of the weight matrix. Design examples are provided to demonstrate the performance of the proposed algorithms.
