这是一个模拟一些简单物理现象的小程序，如小桥过河之类的，运行程序时需要把CCBP文件夹包含在头文件。-This is a simple simulation of the physical phenomena of small programs, such as the bridge across the river like the program to run when the need CCBP folder contains the header files.

这是我大一第二个学期期末制作的软件工程课程设计，逻辑上没有什么太复杂的， 当时学习的东西不是很多，用了链表，其中使用了DOS下汉字直显，无需汉字系统 支持，使用了文件操作，就当时对c语言的联系：）-This my second semester freshman year ending production of software engineering curriculum design, logic, nothing too complicated, not learning a lot of things, the use of linked lists, which use Chinese characters straight DOS significantly without Chinese support system, the use of paper operations, on the prevailing language of c contact :)

一个打砖块的代码，很简单，非常适合出学者-a Dazhuankuai code, which is very simple and very suitable to scholars

这是一段时间vc++学习总结，主要是一些控件使用技巧，对初学者会有一定的帮助。-This is a time vc study concluded that the main component is the use of some techniques for beginners will be of some help.

完整的汇编课程设计报报告，题目为乐曲程序 报告最后为完整的汇编源代码-complete compilation reportedly curriculum design, the theme of the music procedures for the integrity of the final report of a compilation of source code

用C++ builer 实现的关于文件操作经典实例 里面有所有工程需要的源代码-C builer document on the realization of the operation, there are classic examples of all the projects need the source code

升级源码，让局域网内的所以客户机自动升级，文件保存到数据库内，保存前先压缩-escalation source, so the LAN client automatic updates, save the file to the database, the depositary before compression

使用python实现青蛙过河，在程序中调用button与graphics模块，将每个青蛙包装为一个模块，点击后可以判断跳动方向并向左或右移动、以及根据边上青蛙的个数自行判断决定是否越过一只青蛙，当最终所有青蛙成功调换位置后，显示“success”，另外，利用stack实现可后悔之前步骤。

本文首先概述了OFDM 的原理、特征和关键技术，介绍了系统需要的几种同步。然后就同步误差对系统性能的影响进行了简单的分析，表明定时偏差和采样频率偏差将会引入码间干扰，载波频率偏差导致载波间干扰的发生。因此，在OFDM系统接收机中定时的确定、载波频率偏差和采样频率偏差的纠正是信号恢复的关键。之后对OFDM系统同步的几种实现方法进行了介绍，分析了各同步方法的性能。-The paper first outlines the principles of OFDM, features and key technologies, the system needs to introduce several synchronization. Synchronization error and then the impact on system performance for a simple analysis, show that the timing deviation and the sampling frequency deviation will introduce inter-symbol interference, the carrier frequency deviation led to the occurrence of ICI. Therefore, in OFDM system receiver to determine the timing, carrier frequency offset and sampling frequency offset correction signal to restore the key. After the OFDM system to achieve synchronization of several methods of introduction, an analysis of the performance of the synchronization method.
