记录我的一些收藏夹里的东东，很不错的，大家看看吧-record some of my favorites in the Eastern Lane, a very good, we look at it

利用MScomm控件编程实现串口通讯原程序,比较不错,不妨-use MScomm Control Programming serial communication program, quite good to try something

通过ftp下载信息，完整代码，在生产中使用呢；对大家应该有用；-through ftp download information, the integrity of code used in production now. Should be useful to everyone;

虚拟数字化仪的实现，是数字图像处理很好的参考资料。没说的。-Virtual Instrument Digital is true, digital image processing, a good reference. The advocates.

程序使用了自相关性和互相关性较好的gold码作为扩频序列，直扩，扩频增益设置为31，模拟用户数为4-Program uses a self-correlation and cross-correlation of the better gold code as spreading sequence, direct expansion, spreading gain is set to 31 to simulate the number of users of 4
