Exceptions to the Multifractal Formalism for Discontinuous Measures
(19980115)In an earlier paper the authors introduced the <i>inverse measure</i> <i>Âµ</i><sup>â </sup>(<i>dt</i>) of a given measure <i>Âµ</i>(<i>dt</i>) on [0,1] and presented the 'inversion formula' <i>f</i><sup>â </sup>(<i>a</i>) ... 
Exchange Algorithms that Complement the ParksMcClellan Algorithm for Linear Phase FIR Filter Design
(19970201)This paper describes an exchange algorithm for the frequency domain design of linear phase FIR equiripple filters where the Chebyshev error in each band is specified. The algorithm is a hybrid of the algorithm of Hofstetter, ... 
Explicit Lower Bounds of the Hausdorff Dimension of Certain Self Affine Sets
(19950120)A lower bound of the Hausdorff dimension of certain selfaffine sets is given. Moreover, this and other known bounds such as the box dimension are expressed in terms of solutions of simple equations involving the singular ... 
Extending Winograd's Small Convolution Algorithm to Longer Lengths
(19940115)For short data sequences, Winograd's convolution algorithms attaining the minimum number of multiplications also attain a low number of additions, making them very efficient. However, for longer lengths they require a ... 
Fast computation of the slidingwindow Radon transform with application to attribute extraction
(19990115)We have developed a fast and robust algorithm for the extraction of 3D seismic attributes. The algorithm is based on the recursive computation of the 3D slidingwindow Radon transform. Considerable gain in computational ... 
Fast, Exact Synthesis of Gaussian and nonGaussian LongRangeDependent Processes
(20090415)1/f noise and statistically selfsimilar random processes such as fractional Brownian motion (fBm) and fractional Gaussian noise (fGn) are fundamental models for a host of realworld phenomena, from network traffic to ... 
Fast, Exact Synthesis of Gaussian and nonGaussian LongRangeDependent Processes
(19990115)1/<i>f</i> noise and statistically selfsimilar processes such as fractional Brownian motion (fBm) are vital for modeling numerous realworld phenomena, from network traffic to DNA to the stock market. Although several ... 
Faster Sequential Universal Coding via Block Partitioning
(20060401)Rissanen provided a sequential universal coding algorithm based on a block partitioning scheme, where the source model is estimated at the beginning of each block. This approach asymptotically approaches the entropy at the ... 
FFTAccelerated Iterative MIMO Chip Equalizer Architecture For CDMA Downlink
(20050301)In this paper, we present a novel FFTaccelerated iterative Linear MMSE chip equalizer in the MIMO CDMA downlink receiver. The reversed form timedomain matrix multiplication in the Conjugate Gradient iteration is accelerated ... 
Flexible Wavelet Transforms Using Lifting
(19980901)We introduce and discuss biorthogonal wavelet transforms using the lifting construction. The lifting construction exploits a spatialdomain, predictionerror interpretation of the wavelet transform and provides a powerful ... 
FORWARD AND INVERSE MODELS IN ELECTRONEUROLOGY (SPINAL STIMULATION, NEUROGRAPHY, CIRCULAR LIMB, NEUROLOGY, ELECTROPHYSIOLOGY)
(1985)Understanding the behavior of electric fields in animal tissues is essential to a number of clinical topics, including electric stimulation of nerves or muscles, and sensing of nerve potentials for diagnostic purposes. ... 
ForWaRD: FourierWavelet Regularized Deconvolution for IllConditioned Systems
(20040201)We propose an efficient, hybrid <i>FourierWavelet Regularized Deconvolution</i> (ForWaRD) algorithm that performs noise regularization via scalar shrinkage in both the Fourier and wavelet domains. The Fourier shrinkage ... 
Four top reasons why mutual information does not assess neural information processing
(20020720)Mutual information between stimulus and response has been advocated as an information theoretic measure of a neural system's capability to process information. Once calculated, the result is a single number that supposedly ... 
A FourierProny Tauberian Approach to the Analysis of a Mixture of Delayed Signals
(19790920)Let x and y be signals (i.e. realvalued functions of time) of finite duration and energy. In the present paper, we develop a frequency domain Prony approach for interpolating, or in general, approximating y(t) by .... 
An FPGA Based Rapid Prototyping Platform for MIMO Systems
(20031120)There exists a seemingly limitless demand for wireless communications systems capable of higher datarates with lower power consumption. While the demand for improvement in these systems seems limitless, the spectrum ...

(20050601)In this paper we present an FPGAbased daughtercard designed for TIs C6000 family of DSP Starter Kits (DSKs). The hardware, initially designed for a course project, provides a platform for studying heterogeneous systems ... 
Fractional Brownian motion and data traffic modeling: The other end of the spectrum
(19970120)We analyze the fractal behavior of the high frequency part of the Fourier spectrum of fBm using multifractal analysis and show that it is not consistent with what is measured on real traffic traces. We propose two extensions ... 
A Further Investigation on ARVector Models for Text Independent Speaker Identification
(19960101)In this paper, we investigate on the role of dynamic information on the performances of ARvector models for speaker recognition. To this purpose, we design an experimental protocol that destroys the time structure of ...
