作者:邓华 人民邮电出版社 本书着重介绍了MATLAB在通信仿真，尤其是移动通信仿真中的应用，通过丰富具体的实例来加深读者对通信系统仿真的理解和掌握。 全书共分10章，前3章介绍MATLAB通信仿真的基础，包括Simulink和S-函数；第4~8章分别介绍了信源和信宿、信道传输、信源编码、信道编码、信号交织以及信号调制的仿真模块及其仿真实现过程；第9章介绍了在通信系统的仿真和调试过程中经常遇到的问题及其解决办法；最后，第10章以cdma 2000为例介绍了移动通信系统的设计和仿真。(Author: Deng Posts & Telecom Press This book highlights the MATLAB simulation in communication, especially mobile communications simulation, through a rich and specific examples to deepen the reader' s understanding of communication system simulation and control. The book is divided into 10 chapters, the first 3 chapter describes the MATLAB simulation-based communications, including Simulink, and S-functions No. 4 Chapter 8 introduced the letter of the source and places the letter, channel transmission, source coding, channel coding, signal interleaving, and signal Modulation of the Simulation Module and Simulation of the implementation process Chapter 9 describes the communications system simulation and debugging process frequently encountered problems and their solutions Finally, Chapter 10, for example, introduced in order to cdma 2000 mobile communication system design and simulation.)

第一个编程题，首先会用到Timer对五个随机数转动的时间间隔进行控制。然后还要将事件与Enter键进行关联，程序实现了Enter键控制转动的开始和结束的功能。最后还要连接数据库，以便于根据选中的编号从数据库中调出对应的姓名并显示在界面上。第二个编程题中涉及的知识更全面一点，包括资源管理器浏览方式的实现、将Excel表格中的内容导入DataGridView控件中、找出符合题意的抽取方法、将DataGridView控件中的内容导出到Excel表格中并保存等等。但是最关键的还是简单、实用的抽取方法。
