Decision-Feedback Differential Detection in Impulse-Radio Ultra-Wideband Systems
—Building upon recent approaches for detection of impulse-radio ultra-wideband (IR-UWB) based on compressed sensing (CS), we combine this approach with techniques known from adva...

Construction of orthonormal multi-wavelets with additional vanishing moments
An iterative scheme for constructing compactly supported orthonormal (o.n.) multi-wavelets with vanishing moments of arbitrarily high order is established. Precisely, let = [1,
