Optimal tree node ordering for child/descendant navigations
Abstract— There are many applications in which users interactively access huge tree data by repeating set-based navigations. In this paper, we focus on label-specific/wildcard c...

On Lowering the Error Floor of High Order Turbo BICM Schemes Over Fading Channels
— A new approach for the association of the well known turbo codes to modulation schemes is presented. This method is designed for flat fading channels. It presents the advantage...

Complete Parametrization of Piecewise Polynomial Interpolators According to Degree, Support, Regularity, and Order
The most essential ingredient of interpolation is its basis function. We have shown in previous papers that this basis need not be necessarily interpolating to achieve good result...
