该程序实现水声信道的模拟方法及性能分析，提出了一种信的水声信道模型(The program implements underwater acoustic channel simulation methods and performance analysis, presents a letter of underwater acoustic channel model)

MODBUS RTU using Attiny44 from Atmel

用Visual C++的API函数来打开、关闭串口和设置串口通讯速率等功能。(Visual C++ using the API function to open and close the serial port and set up features such as serial communication rate.)

模仿超级终端风格的RS232串口调试工具 这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。 里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load. Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)

说明：  TCP/ip通讯客户端的程序。VB程序编写WINSOCK控件应用(TCP/ip messaging client program. VB programming WINSOCK Control Applications)

基于VC++ 6.0 Winsock+UDP 广播信息源码(Based on VC++ 6.0 Winsock+ UDP broadcast source)

本论文以OFDM系统为基础，介绍了OFDM系统的基本原理，以及使用OFDM技术的优势所在，并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时，着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道，在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能，其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础 (This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)
