rayleighnew
瑞利衰落信道,是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后,其信号幅度是随机的,即“衰落”,并且其包络服从瑞利分布。这一信道模型能够描述由电离层和对流层反射的短波信道,以及建筑物密集的城市环境。(Rayleigh fading channels, the statistical model of a radio signal propagation environment. This model assumes that after the signal through the radio channel, the signal amplitude is random, ie, the " fading" and the envelope of the Rayleigh distribution. This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment.)

vb.RS232
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.)
