摘要：
Traditional designs for nonuniform filter banks usually involve complicated nonlinear optimization with a large number of parameters. A simple design approach that involves the optimization of only single parameter is presented for the design of nonuniform cosine. modulated filter bank, which is derived by combination of filters in uniform cosine modulated filter banks. The prototype filter is formulated as an interpolated FIR filter and is indirectly designed by varying the passband edge of a low-order model filter. A design example is presented to show that very good design can be obtained in spite of the limit of the formulation.
