Efficient design of cosine-modulated filter banks
Esam Abdel‐Raheem, F. El-Guibaly, A. Antoniou · 2002
An iterative algorithm presented by Lim, Yang, and Koh (see IEEE Trans. Signal Processing, vol.41, p.1780-1789, 1993) is extended for the design of cosine-modulated pseudo-filter banks. The algorithm is simple, efficient, and results in savings in the amount of computation and design time. Design examples are included to illustrate the method.
