MBand Multiwavelet Systems
(19990320)In this paper we investigate multiwavelet systems whose scaling functions have disjoint support. We demonstrate that, with the exception of a trivial case, this property may not be attained by two band multiwavelet systems. ... 
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(19940501)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w)  F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... 
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(19941001)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w)  F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... 
Magnitude Weighting and Time Segmentation for PhaseOnly Reconstruction of Signals
(19810401)Phaseonly reconstruction of signals and its application to blinddeconvolution were introduced recently by Oppenheim, and by Hayes, et.al. In this report, we briefly present another description of this phaseonly ... 
Marginals vs. Covariance in Joint Distribution Theory
(19950501)Recently, Cohen has proposed a method for constructing joint distributions of arbitrary physical quantities, in direct generalization of joint timefrequency representations. In this paper, we investigate the covariance ... 
A Markov Chain Analysis of Blackjack Strategy
(20040701)Blackjack receives considerable attention from mathematicians and entrepreneurs alike, due to its simple rules, its inherent random nature, and the abundance of "prior" information available to an observant player. Many ... 
Matrix Based Computation of FloatingPoint Roundoff Noise
(19891201)A matrix based procedure is presented for computing the output roundoff noise power for filters implemented with floatingpoint arithmetic. The filter's computational structure is represented in terms of a product of ... 
Measurements vs. Bits: Compressed Sensing meets Information Theory
(20060901)Compressed sensing is a new framework for acquiring sparse signals based on the revelation that a small number of linear projections (measurements) of the signal contain enough information for its reconstruction. The ... 
Measuring TimeFrequency Information and Complexity using the Renyi Entropies
(19950901)In search of a nonparametric indicator of deterministic signal complexity, we link the Renyi entropies to timefrequency representations. The resulting measures show promise in several situations where concepts like the ... 
Measuring TimeFrequency Information Content using the Renyi Entropies
(20010501)The generalized entropies of Renyi inspire new measures for estimating signal information and complexity in the timefrequency plane. When applied to a timefrequency representation (TFR) from Cohen's class or the affine ... 
Minimax support vector machines
(20070801)We study the problem of designing support vector machine (SVM) classifiers that minimize the maximum of the false alarm and miss rates. This is a natural classification setting in the absence of prior information regarding ... 
Modelbased Inverse Halftoning with WaveletVaguelette Deconvolution
(20000901)In this paper, we demonstrate based on the linear model of Kite that inverse halftoning is equivalent to the wellstudied problem of deconvolution in the presence of colored noise. We propose the use of the simple and ... 
Modeling wireless sensor and actuator networks using frame theory
(20051101)Wireless sensor networks are often studied with the goal of removing information from the network as efficiently as possible. However, when the application also includes an actuator network, it is advantageous to determine ... 
Multifractal CrossTraffic Estimation
(20000901)In this paper we develop a novel modelbased technique, the Delphi algorithm, for inferring the instantaneous volume of competing crosstraffic across an endtoend path. By using only endtoend measurements, Delphi avoids ... 
Multifractal Formalism for Infinite Multinomial Measures
(19950120)There are strong reasons to believe that the multifractal spectrum of DLA shows anomalies which have been termed left sided. In order to show that this is compatible with strictly multiplicative structures Mandelbrot et ... 
Multifractal products of stochastic processes: construction and some basic properties
(20020115)In various fields, such as teletraffic and economics, measured times series have been reported to adhere to multifractal scaling. Classical cascading measures possess multifractal scaling, but their increments form a ... 
Multifractal Properties of TCP Traffic: a Numerical Study
(19971020)We analyze two traces of TCPtraffic recorded at the gateway of a LAN correÂ sponding to two hours at Berkeley and to eight hours at CNET labs respectively. We are mainly interested in a multifractal approach, which we ...
