Spectral Optimization for Communication in the Presence of Crosstalk
This paper presents a general framework for designing optimal transmit spectra for communication services dominated by crosstalk --- for example Digital Subscriber Lines (DSLs) and wireless LANs. Using the channel, noise, ...
Implementation of Channel Estimation and Multiuser Detection Algorithms for W-CDMA on Digital Signal Processors
Proposed algorithms for Third Generation W-CDMA communication systems have extremely high performance requirements. In this paper, we study the implementation issues involved for one of the proposed multiuser channel ...
Wavelet-Based Transformations for Nonlinear Signal Processing
Nonlinearities are often encountered in the analysis and processing of real-world signals. In this paper, we introduce two new structures for nonlinear signal processing. The new structures simplify the analysis, design, ...
Wavelet-Based Deconvolution Using Optimally Regularized Inversion for Ill-Conditioned Systems
We propose a hybrid approach to wavelet-based deconvolution that comprises Fourier-domain system inversion followed by wavelet-domain noise suppression. In contrast to conventional wavelet-based deconvolution approaches, ...
Detection of Target Speakers in Audio Databases
The problem of speaker detection in audio databases is addressed in this paper. Gaussian mixture modeling is used to build target speaker and background models. A detection algorithm based on a likelihood ratio calculation ...
Hybrid Linear / Bilinear Time-Scale Analysis
We introduce a new method for the time-scale analysis of non-stationary signals. Our work leverages the success of the "time-frequency distribution series / cross-term deleted representations" into the time-scale domain ...
Fast, Exact Synthesis of Gaussian and nonGaussian Long-Range-Dependent Processes
1/<i>f</i> noise and statistically self-similar processes such as fractional Brownian motion (fBm) are vital for modeling numerous real-world phenomena, from network traffic to DNA to the stock market. Although several ...
A Multifractal Wavelet Model with Application to Network Traffic
In this paper, we develop a new multiscale modeling framework for characterizing positive-valued data with long-range-dependent correlations (1/f noise). Using the Haar wavelet transform and a special multiplicative structure ...
