• ### Nonlinear Bayesian Filtering Using the Unscented Linear Fractional Transformation Model

Publication Year: 2010, Page(s):477 - 489
Cited by:  Papers (16)
| |PDF (403 KB) | HTML

For nonlinear state space model involving random variables with arbitrary probability distributions, the state estimation given a sequence of observations is based on an appropriate criterion such as the minimum mean square error (MMSE). This leads to linear approximation in the state space of the extended Kalman filter (EKF) and the unscented Kalman filter (UKF), which work reasonably well only f... View full abstract»

• ### Adaptive Threshold Estimation via Extreme Value Theory

Publication Year: 2010, Page(s):490 - 500
Cited by:  Papers (11)
| |PDF (652 KB) | HTML

Determining a detection threshold to automatically maintain a low false alarm rate is a challenging problem. In a number of different applications, the underlying parametric assumptions of most automatic target detection algorithms are invalid. Therefore, thresholds derived using these incorrect distribution assumptions do not produce desirable results when applied to real sensor data. Monte Carlo... View full abstract»

| |PDF (392 KB) | HTML

In this paper, we examine the estimation of the parameters of a decaying complex exponential in noise. The strategy adopted consists of a computationally simple two stage scheme where an interpolation stage refines the coarse estimate obtained from an initial maximum bin search. The interpolators of Quinn, and of Aboutanios and Mulgrew, developed for undamped exponentials are extended to the dampe... View full abstract»

• ### Noisy Data and Impulse Response Estimation

Publication Year: 2010, Page(s):510 - 521

| |PDF (584 KB) | HTML

This paper investigates the impulse response estimation of linear time-invariant (LTI) systems when only noisy finite-length input-output data of the system is available. The competing parametric candidates are the least square impulse response estimates of possibly different lengths. It is known that the presence of noise prohibits using model sets with large number of parameters as the resulting... View full abstract»

This paper derives the asymptotic analytical forms of the mean and variance of the Gini correlation (GC) with respect to samples drawn from bivariate normal populations. The asymptotic relative efficiency (ARE) of the Gini correlation to Pearson's product moment correlation coefficient (PPMCC) is investigated under the normal assumptions. To gain further insight into GC, we also compare the Gini c... View full abstract»

| |PDF (919 KB) | HTML

Communication applications are increasingly relying on spread-spectrum techniques requiring the use of different types of pseudorandom noise generators (PRNGs). Such generators typically produce periodic deterministic signals, with key attributes of PRNGs being: signals produced have long periods, a large number of weakly correlated signals is produced with compatible spectral properties, most of ...

• ### Anomaly Preserving $ell _{scriptscriptstyle 2,infty }$-Optimal Dimensionality Reduction Over a Grassmann Manifold

Publication Year: 2010, Page(s):544 - 552
Cited by:  Papers (3)
| |PDF (690 KB) | HTML

In this paper, we address the problem of redundancy reduction of high-dimensional noisy signals that may contain anomaly (rare) vectors, which we wish to preserve. Since anomaly data vectors contribute weakly to the l2-norm of the signal as compared to the noise, l2 -based criteria are unsatisfactory for obtaining a good representation of these vectors. As a remedy, a new app... View full abstract»

• ### Welch Method Revisited: Nonparametric Power Spectrum Estimation Via Circular Overlap

Publication Year: 2010, Page(s):553 - 565
Cited by:  Papers (26)
| |PDF (728 KB) | HTML

The objective of this paper is twofold. The first part provides further insight in the statistical properties of the Welch power spectrum estimator. A major drawback of the Welch method reported in the literature is that the variance is not a monotonic decreasing function of the fraction of overlap. Selecting the optimal fraction of overlap, which minimizes the variance, is in general difficult si... View full abstract»

We employ the concepts and tools of the discrete wavelet transform (DWT) to encapsulate a body of previous research on efficiently analyzable phase-coded waveforms for use in ranging applications. This DWT perspective enables the direct synthesis of half-rate implementations which are suitable for high-speed applications. We introduce and study a set of sequences, based on a classical Welti constr... View full abstract»

| |PDF (366 KB) | HTML

We propose a parameterization of the finite-impulse-response (FIR) filters that generate the higher density discrete wavelet transform (HD-DWT). The parameterization has the form of a linear system whose variables are the coefficients of two positive trigonometric polynomials. The parameterization allows the easy separation of independent variables and can be used to transform the optimization of ... View full abstract»

| |PDF (567 KB) | HTML

The generalizations of instantaneous frequency and instantaneous bandwidth to a bivariate signal are derived. These are uniquely defined whether the signal is represented as a pair of real-valued signals or as one analytic and one anti-analytic signal. A nonstationary but oscillatory bivariate signal has a natural representation as an ellipse whose properties evolve in time, and this representatio... View full abstract»

The self-duality of short-time Fourier transform (STFT) is an elegant property and is useful in shedding light on the construction of STFT and its resolution capability. In this paper, the discrete version of self-duality is studied, and the property is interpreted in the context of resolution capabilities of time frequency distributions. In addition, two applications are provided as showcases of ... View full abstract»

| |PDF (594 KB) | HTML

We consider the problem of sampling piecewise sinusoidal signals. Classical sampling theory does not enable perfect reconstruction of such signals since they are not band-limited. However, they can be characterized by a finite number of parameters, namely, the frequency, amplitude, and phase of the sinusoids and the location of the discontinuities. In this paper, we show that under certain hypothe... View full abstract»

| |PDF (1174 KB) | HTML

We introduce a unified approach for calculating nonparametric shape constrained regression. Enforcement of the shape constraint often accounts for the impact of a physical phenomenon or a specific property. It also improves the model's predicability and facilitates subsequent optimizations. The regression models are built by transforming the problem into the combinatorial domain where the shape co... View full abstract»

A new family of cumulant-based algorithms is proposed in order to blindly identify potentially underdetermined mixtures of statistically independent sources. These algorithms perform a joint canonical decomposition (CAND) of several higher order cumulants through a CAND of a three-way array with special symmetries. These techniques are studied in terms of identifiability, performance and numerical... View full abstract»

In this paper, we present multiple novel applications for local intrinsic dimension estimation. There has been much work done on estimating the global dimension of a data set, typically for the purposes of dimensionality reduction. We show that by estimating dimension locally, we are able to extend the uses of dimension estimation to many applications, which are not possible with global dimension ... View full abstract»

Consider a downlink communication system where multiantenna base stations transmit independent data streams to decentralized single-antenna users over a common frequency band. The goal of the base stations is to jointly adjust the beamforming vectors to minimize the transmission powers while ensuring the signal-to-interference-noise ratio requirement of each user within the system. At the same tim... View full abstract»

In this pair of papers (Part I and Part II in this issue), we investigate the issue of power control and subcarrier assignment in a sectorized two-cell downlink OFDMA system impaired by multicell interference. As recommended for WiMAX, we assume that the first part of the available bandwidth is likely to be reused by different base stations (and is thus subject to multicell interference) and that ...
