We present a new method to design prototype filters for conventional cosine-modulated pseudo-quadrature mirror filter (QMF) banks. This method is based on windowing, and sets the 3-dB cutoff frequency of the filter obtained at pi/2M. In this way, the filter bank performance can be significantly improved compared to other existing design methods.
