Описание: Nonlinear Signal Processing: A Statistical Approach focuses on unifying the study of a broad and important class of nonlinear signal processing algorithms which emerge from statistical estimation principles, and where the underlying signals are non-Gaussian, rather than Gaussian, processes. Notably, by concentrating on just two non-Gaussian models, a large set of tools is developed that encompass a large portion of the nonlinear signal processing tools proposed in the literature over the past several decades. Key features include: *Numerous problems at the end of each chapter to aid development and understanding *Examples and case studies provided throughout the book in a wide range of applitions bring the text to life and place the theory into context *A set of 60+ MATLAB software m-files allowing the reader to quickly design and apply any of the nonlinear signal processing algorithms described in the book to an application of interest is available on the accompanying FTP site.
Описание: Bandwidth extension of signals may be defined as the deliberate processexpanding the frequency range (bandwidth) of a signal in which it contains an appreciable and useful content, and/or the frequency range in which its effects are such. Its significant advancement in recent years has led to the technology being adopted commercially in several areas including psychacoustic bass enhancement of small loudspeakers and the high frequency enhancement of perceptually coded audio. The increasing use of this technology in different areas creates a need for knowledge of the area. Written by an expert in the field, Signal Bandwidth Extension for Applications in Audio Signal Processing will consolidate the theories and applications surrounding signal bandwidth extension to help the reader develop a comprehensive knowledge of the area and its potential uses. An ideal reference for academics and professionals alike, it will be most suited to researchers and developers in audio engineering. However, it will also be suitable for those studying or working in areas such as signal processing, communications, audio and video engineering and coding theory

Описание: This book addresses the concepts and applications of signal and image data transformation that can be implemented mathematically by vector, matrix, and linear algebra methods. The major motivating application is signal and image compression, and the major implementing software is MATLAB. The authors have simplified the concepts and presentation, which allows students to move from the mathematical models to the applications more quickly. Moreover, the ideas can be implemented in MATLAB in a straightforward way. The authors successfully explain terms that may be unfamiliar to readers, and they also explain mathematical concepts that are relevant to image compression and signal processing. Most of the competing texts focus on the concepts of imaging science and algorithms while Broughton and Bryan's book is more focused on the underlying mathematics, with image compression as a motivation. This book is not a straight theorem-proof mathematical treatise, nor a cookbook of algorithms. A Student Solutions Manual is available, and a related Web site offers additional supplementary material such as additional MATLAB projects.

Описание: Field-Programmable Gate Arrays (FPGAs) are revolutionizing digital signal processing as novel FPGA families are replacing ASICs and PDSPs for front-end digital signal processing algorithms. So the efficient implementation of these algorithms is critical and is the main goal of this book. It starts with an overview of today's FPGA technology, devices, and tools for designing state-of-the-art DSP systems. A case study in the first chapter is the basis for more than 40 design examples throughout. The following chapters deal with computer arithmetic concepts, theory and the implementation of FIR and IIR filters, multirate digital signal processing systems, DFT and FFT algorithms, advanced algorithms with high future potential, and adaptive filters. Each chapter contains exercises. The VERILOG source code and a glossary are given in the appendices, while the accompanying CD-ROM contains the examples in VHDL and Verilog code as well as the newest Altera "Quartus II web edition" software. This edition has a new chapter on microprocessors, new sections on special functions using MAC calls, intellectual property core design and arbitrary sampling rate converters, and over 100 new exercises.
Описание: Digital Design of Signal Processing Systems offers a practical guide to designing efficient digital systems, covering the complete spectrum of digital design from a DSP (digital signal processing) perspective.
