代码说明:

  对于移动通信系统主要有两类衰落:大规模衰落和小规模衰落。大规模衰落表示由于大范围内移动而引起的平均信号能量的减少或路径损耗。而小规模衰落则表现为两种机制:信号的时延扩展和信道的时变特性。对于无线应用,信道的时变特性是由于发射机和接收机相对移动而造成传输路径的变化。这些传播条件的变化速率影响衰落率。如果存在大量反射路径而不存在视行信号分量,此时的小规模衰落称为瑞利衰落(Rayleigh fading),接收信号的包络由瑞利概率分布函数统计描述。这种衰落也就是这次实验我准备研究的(system for mobile communications fading there are two main categories : large-scale and small-scale fading fading. In view of large-scale decline of large scale movement of the average energy of the signal path to reduce or loss. And the decline of small-scale, it was manifested as two mechanisms : signal delay expansion and channel time-varying characteristics. For wireless applications, channel time-varying characteristics as transmitter and receiver relative movement caused transmission path changes. These conditions spread of the rate changes affect the rate of decline. If there is a large number of pathways exist without depending on the signaling component, At that time, the decline of small-scale known as Rayleigh fading (Rayleigh fading). The received signal envelope from Rayleigh )

    ex9_14 雷达的恒虚警处理(CFAR)。在雷达的数据中有很多的杂波,会造成虚警。所以我们必须进行处理,这里我们采用了慢门处理和快门处理,并且对处理后的结果进行比较(ex9_14 radar CFAR processing (CFAR). The radar data have a lot of clutter, this will result in false alarms. Therefore, we must deal with, here we have adopted a slow shutter door handle and deal with, and after the results were compared)

  • ch1
    本书基于MATLAB 5.2版,提供了使用MATLAB的实践性指导。MATLAB已成为适合多学科、多种工作平台的功能强大、界面友好、语言自然并且开放性强的大型优秀应用软件,同时也已成为国内外高等院校高等数学、数值分析、数字信号处理、自动控制理论以及工程应用等课程的基本教学工具。本书按逻辑编排,自始至终用实例描述;内容完整且每章相对独立;是一本简明的MATLAB参考书,既适用于初学者,也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所有MATLAB书籍中少有的一大特色。 本书适合作为理工科高等院校研究生、本科生教学用书,也可作为广大科研工程技术人员的自学用书。
