商品描述

Description:

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 applications 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.

描述:



《非線性信號處理:統計方法》專注於統一研究一類重要的非線性信號處理算法,這些算法源於統計估計原理,並且底層信號是非高斯過程,而不是高斯過程。值得注意的是,通過專注於兩個非高斯模型,我們開發了一套工具,涵蓋了過去幾十年來文獻中提出的大部分非線性信號處理工具。


主要特點包括:



  • 每章末尾提供大量問題,以幫助讀者發展和理解

  • 書中提供了各種應用領域的例子和案例研究,使理論具體化並置於上下文中

  • 附帶的FTP站點上提供了60多個MATLAB軟件m文件,讀者可以快速設計和應用書中描述的任何非線性信號處理算法到感興趣的應用中
