MATLAB代码，产生GNSS导航信号BOC调制的相关频谱特性(The generate of BOC signal AND ITS PDF)

说明：  1）分页环境 Xshell标签可以脱离原来的窗口并重新创建一个新窗口或重新连接一个完全不同的窗口。另外，单个的窗口可以垂直或水平分割，从而使一个窗口显示多个终端会话。 2）动态端口转发 系统管理员经常必须使用多个远程主机，并沉闷的一遍又一遍的执行重复的任务。使用新的同步输入重定向特性，所输入的东西能够同时发送到多个所选择的终端。 3）自定义键映射 终端密钥和文件菜单可以被映射到用户偏爱的键位，你甚至可以映射一个用来启动应用程序或脚本的键。 4）用户定义按钮 通常，用户必须多次重复输入相同的字符串。而xshell只需要点击按钮就可以完成重复字符串命令的输入，快速命令能够节省很多时间。 5）VB脚本(XShell, free and safe download. XShell latest version: Free terminal emulator for personal and professional use. XShell is an Internet & Network)

Introduction to Computational Plasticity, 作者：Fionn Dunne and Nik Petrinic. 发表年份：2005. 一本非常基础和使用的介绍计算塑性力学的书籍。(Introduction to Computational Plasticity, written by Fionn Dunne and Nik Petrinic. Published in 2005. A very basic and detailed book that introduces computational plasticity.)

研究了一种数字中频 GPS 信号生成方法。给出了数字中频信号数学模型，模型考虑了各种因素对信号的影响。通过导航电文分析，提出信号传播时延、多普勒频移以及信号入射方向的估计方法。给出了中频信号产生的流程，对其中时延的设置，信号的上变频、信号幅度设置以及方向信息的导入进行了阐述。对所生成的信号模型进行了仿真分析，给出了信号产生各个阶段的频谱，对所生成的信号进行了相关捕获。仿真结果表明频谱特征符合理论分析，能够被捕获并找出信号时延从而实现定位。证明该信号模型能作为信号源应用于 GPS接收机研制中。(】The paper discusses a digital IF GPS signal generation method, gives the mathematic model of digital IF signal. This mathematic model takes into account the influence of various factors. Based on analysis of the navigation data, the method to estimate signal propagation time, Doppler frequency shift and the coming angle of signal is proposed. The flow to generate IF signal is given, in which the setting of time delay, the up-frequency conversion, the setting of signal magnitude and the introduction of direction information are expounded. The signal generation model is simulated and analyzed, the spectrum of signal in each stage given, and the correlation capture of the generated signal also done. Simulation indicates that the spectrum is in accord with theoretical analysis the signal could be captured, thus find the time delay, accomplish the orientation. The signal model is proved applicable in the research and development of GPS receiver.)
