A Kaiser window approach for the design of prototype filters of cosine modulated filterbanks
Abstract
The traditional designs for the prototype filters of cosine modulated filterbanks usually involve nonlinear optimizations. We propose limiting the search of the prototype filters to the class of filters obtained using Kaiser windows. The design process is reduced to the optimization of a single parameter. An example is given to show that very good designs can be obtained in spite of the limit of search.
