说明：  ：载波频率偏移是OFDM系统实现的关键问题之一。分析了OFDM 系统载频偏移估计的2 种算法，即利用循环前缀和训练序列方法。它们均为最大似然估计方法。分别讨论了它们的基本 思想、实现方法和仿真结果。可以看出基于循环前缀算法复杂度较小，精度不高，而基于训练序列 的算法有较高的估计精度，但降纸了系统传输效率。(Abstract：Carrier frequency ofset is one of the key problems in OFDM system．Two foundational methods 。cycling prefix—based and training sequence—based algorithms。to estimate OFDM carriers~equency ofset are analyzed．Then it discusses their basic thoughts。implementing methods and simulation resuits． Finally。merits and demerits of every algorithm are supposed．It concludes that the cycling prefix— based algorithm has less complexity and less precision。and that the training sequence—based algorithm has better estimation performance at the cost of transmission efficiency．)

数组可以存放5个人的姓名，每个姓名包括first name，middle name和last name，输出姓名时，其中middle name只取大写的首字母，利用索引编写程序，使得用户输入last name后，输出姓名的全称。(array can store the names of five individuals, including the names of each first name, middle name and last name, the name of the output, which only middle name from the first uppercase letter, the use of indexing programming, enabling users to import last name, the name of the generic output.)

说明：  最简单的收发程序，可以用于超宽带测距，信道通信等等(The simplest transceiver program can be used in UWB ranging, channel communication and so on)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

一个与仪表通讯的上位机程序源码，采采用RS232通讯，协议为MODBUS (A host computer program source code with the instrument of communication, mining RS232 communication protocol MODBUS)
