... in the passband but also in the transition band. The mean value of the group delay ranges below that of linear-phase filters of the same length. The observed overall signal delay lies within the ... oversampling uniform complex-modulated FIR filter bank pairs in order to achieve the lowest possible filter bank delay. An illustrative design example demonstrates...

This theoretical analysis, which uses a statistical approach, allows to predict the number ... task. However, there is a clever way to extract information from this matrix without going into involved mathematical anal- ysis. The idea is to optimize the abo...

The new approach is based on a kernel machine ... notation. Radial kernels have a natural interpretation in terms of measure of similarity in X, as the kernel value is larger the closer together two locations are....
