qpsk的matlab程序，描述了qpsk的仿真和理论的误码率误比特率(qpsk matlab program, qpsk simulation and theoretical description of the error rate, bit error rate)

本章有三个目的：一是讲述 MATLAB正常运行所必须具备的基础条件；二是简明地介 绍MATLAB及其操作桌面Desktop的基本使用方法；三是全面介绍 MATLAB的帮助系统。 本章的前两节讲述：MATLAB的正确安装方法和 MATLAB 环境的启动。因为指令窗 是MATLAB最重要的操作界面，所以本章用第 1.3 、1.4 两节以最简单通俗的叙述、算例 讲述指令窗的基本操作方法和规则。这部分内容几乎对MATLAB各种版本都适用。第1.5 到第1.8 节专门介绍 MATLAB最常用的另五个交互界面：历史指令窗、当前目录浏览器、 工作空间浏览器、数组编辑器、M 文件编辑器。 鉴于实际应用中，帮助信息和求助技能的 重要性。本章专设第1.9节专门叙述MATLAB的帮助体系和求助方法。 作者建议：不管读者此前是否使用过MATLAB，都不要忽略本章。(This chapter has three purposes: one is about MATLAB normal operation must have the basic conditions 2 it is concisely interface Salt MATLAB and its operation is the basic way of using the Desktop Desktop Three is a comprehensive introduction of MATLAB help system. About the first two sections in this chapter: MATLAB installation method and the MATLAB environment right start. Because the instructions window Is the most important interface of MATLAB, so this chapter with 1.3 and 1.3 two accounts in the most simple and popular, example Basic operation methods and rules about command window. This part of almost all versions of MATLAB. 1.5 To section 1.8 on another five interfaces: the most commonly used MATLAB command window, the current directory browser history, The workspace browser, array editor, M file editor. In view of practical applications, the help information and skills for help Importance. Set up in section 1.9 of this chapter specifically address the MATLAB help syst)

说明：  模型阶次的辨识,各种模型参数辨识方法一般需要假定模型的结构已知，实际上在多数情况下这是不现实的。当没有模型结构的先验知识时，需要利用系统的输入输出数据来确定模型的结构。(Identification of various model parameters generally need to assume that the model structure is known, in fact, in most cases this is unrealistic. When no prior knowledge of model structure, the need to use the system input and output data to determine the model structure.)

说明：  《载波相位相对定位双差方程原理》验证 《载波相位相对定位单差方程原理》验证 《载波相位相对定位双差方程原理》验证 《载波相位相对定位双差方程原理》验证当基站离流动站很近，并假设流动站概略坐标等于基站坐标，那么双差方程中距离向量就为0(&quot Double difference carrier phase relative positioning equation theory&quot test &quot single-difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation principle&quot is verified when the base station from the mobile station near, and assuming that mobile station is equal to the base station coordinates approximate coordinates, so double-differential equation from the vector is 0)
