Differential unitary space-time modulation
TLDR
We present a framework for differential modulation with multiple antennas across a continuously fading channel, where neither the transmitter nor the receiver knows the fading coefficients. Expand

The Lifting Scheme: A Custom - Design Construction of Biorthogonal Wavelets "Industrial Mathematics
A control circuit for a fuel ignition system of the direct ignition type for providing an interlock on start-up to prevent the energization of a fuel supply valve of the system under certain failureExpand

The lifting scheme: a construction of second generation wavelets
TLDR
We present the lifting scheme, a simple construction of second generation wavelets; these are wavelets that are not necessarily translates and dilates of one fixed function; they can be adapted to intervals, domains, surfaces, weights, and irregular samples. Expand

Factoring wavelet transforms into lifting steps
This article is essentially tutorial in nature. We show how any discrete wavelet transform or two band subband filtering with finite filters can be decomposed into a finite sequence of simpleExpand

Systematic design of unitary space-time constellations
TLDR
We propose a systematic method for creating constellations of unitary space-time signals for multiple-antenna communication links using a Rayleigh fading channel where neither the transmitter nor the receiver knows the fading coefficients. Expand

Wavelet Transforms That Map Integers to Integers
Abstract Invertible wavelet transforms that map integers to integers have important applications in lossless coding. In this paper we present two approaches to build integer to integer waveletExpand

MAPS: multiresolution adaptive parameterization of surfaces
TLDR
An irregular connectivity mesh representative of a surface having an arbitrary topology is processed to generate a parameterization which maps points in a coarse base domain to points in the mesh. Expand
