摘要：

An efficient two-step approach is presented for designing two-channel perfect-reconstruction linear-phase FIR filter banks. The first step involves finding a good solution by using an iterative procedure. This iterative procedure is generated by properly modifying the Lagrange-Newton method proposed by Horng and Willson. In the second step, the resulting solution is then used as a good initial solution for further optimization that is carried out by the second algorithm of Dutta and Vidyasagar. Several examples are included illustrating the efficiency of the proposed approach and the resulting two-channel filter banks.
