近日从网上下载一VB实现异步串口通讯的文章,很实用,特与大家共享.-recently downloaded from the Internet a VB asynchronous serial communication articles very useful, especially to share with you.

A 64 sub carrier OFDM system based on the parameter of Mean square error

基于训练序列的OFDM信道估计仿真程序，可直接运行-Training sequence based on the OFDM channel estimation simulation program can be run directly

移动通信信道配置两种方式的C语言实现，里面还附了一篇报告-Channel configuration in two ways to achieve the C language, which is also included in a report

使用Visual Basic 6实现真正实用的多线程串行通讯 事实上使用Visual Basic的ActiveX exe技术可以轻松的实现多线程处理，此技术在串行通讯中很好用，尤其需要一边通讯，一边数据处理方面，如果用timer实现串行通讯，其复杂程度可想而知。这个实例用在PC与PLC通讯以及PC和单片机通讯，都比较实用。 原理先不说了,先举个示例,有兴趣的话大家可以一起讨论

这是XMODEM传输协议原代码,测试只能证明错误的存在，而不能表明程序中没有错误。 测试的两个作用是：确定程序中缺陷的存在；有助于判断该程序在实际上是否可用。 软件测试最困难的问题之一是知道何时停止测试(When to stop testing? ) 自己测试自己的程序是不可能的。 当一个软件被测出的缺陷数目增加时，更多的未被发现的缺陷存在的概率也随之增加。 -This XMODEM transfer protocol source code, the test can only be proved wrong there and not show anything wrong procedure. The two test role is : procedures for determining the existence of defects; Contribute to the judge whether the procedure can be used in practice. Software testing the most difficult one of the problems is to know when to stop testing (When to stop testing) testing their own procedures is not possible. When a software detected the increase in the number of defects, more undiscovered flaws in the probability has increased.

一个基于dct变换的数字水印算法的源程序,可供进行数字水印学习和研究的学生及科研工作者学习参考-DCT-based digital watermarking algorithm transform the source code, available for study and research of digital watermarking students and researchers to study the reference

信号编码与译码中的二值图像游程编码算法的Matlab实现，谢谢~-Signal encoding and decoding the binary image run-length coding algorithm Matlab implementation, thank you ~

With using noisy data and created data, soft and hard decision are made by viterbi decoder

本程序是利用VB的Winsock控件来实现网络中两台计算机的通信.-this program is to use VB Winsock Control to achieve two computer network communications.
