Content Description

《Simulink与信号处理》（第2版）一书是学习和使用Simulink对信号处理系统进行模拟和仿真的参考书籍,是笔者对多年来在MathWorks工作期间与公司软件开发人员及众多用户交流、切磋获得的经验、体会的总结和提炼。全书共8章,介绍了Simulink的基本知识和Simulink的扩展之一———DSP系统工具箱(DSPSystenToolbox),并按照一般信号处理系统的组成方式和信号流程介绍如何用Simulink建立系统模型———包括信号的产生,信号的滤波,信号的统计参数与信号估计,以及如何在Simulink系统模型中实现复杂的数字信号处理算法。本书的重要特点是在讨论信号处理系统建模时采用了大量实例。全书共提供了近100个Simulink模型文件,是学习Simulink软件,掌握模块特点和应用场合,进而建立复杂信号处理系统模型的宝贵参考资料。这本书的另一个重要特点是涉及面广,取材新颖、实用。本书还特别介绍了Simulink近几年引入的几个重要元素,如传统代码工具和在Simulink中使用MATLAB代码生成器从MATLAB程序自动生成C代码等。本书可以作为电气工程、自动控制及其他专业老师、学生,及相关工程技术人员的参考用书。

Introduction

前言
《Simulink与信号处理》一书出版至今已将近4年了。这期间,MATLAB®/Simulink® ①
这一科学计算、动态系统的模拟与仿真工具发生了很多变化,因此有必要对这本书作修订。从
2011年的春季版本(R2011a)起,MATLAB/Simulink的扩展系列中与信号处理和数字通信有
关的产品出现了重整和组合,发生了很大的变化。原有的信号处理模块集(SignalProcessing
Blockset)与滤波器设计工具箱(FilterDesignToolbox)合并,并且与添加的众多系统客体
(SystemObjects)组成了DSP系统工具箱(DSPSystemToolbox)。系统客体是对采用Math-
Works客体导向编程(ObjectOrientedPrograming)技术编写的算法的统称。修订后的《Simulink
与信号处理》仍然着重关注DSP系统工具箱中用于Simulink的信号处理模块。
本书附赠的所有Simulink模型已经全部升级到R2013a版本,请读者登录MATLAB 中文
论坛“MATLAB读书频道”本书相应版块免费下载该文件包,下载地址:https://www.ilovematlab.
cn/forum 187 1.html,或者致信shpchen2004@163.com 申请索取。在该文件包里,一
个名为xyz的Simulink模型有3个Simulink文件与之对应,它们分别为xyz.mdl、xxyz.slx.
r2013a和xyz.mdl.r2009a。前2个都是版本为R2013a的Simulink模型文件,最后1个是版
本为R2009a的Simulink模型文件。
衷心感谢北京航空航天大学出版社的编辑们为这本书的出版提供的支持。
