双串口调试程序
应用背景采用多线程串口通信，占用系统资源极小，自动获取系统串口（实际、虚拟、usb、串口服务器等），开一个程序可以开启两个串口通信界面，尤其方便自发自收，能够自动保存数据，方便多串口调试尤其是单片机开发者使用关键技术本程序采用多线程串口通信类cxComm.h，通过注册表自动获取系统串口（实际、虚拟、usb、串口服务器等），可读取最大256串口号，支持中文发送接收，支持ascii码和16进制通信

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with
high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s
classical formula scales as one more bit/cycle for every 3 dB of signaltonoise
ratio (SNR) increase, remarkably
withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this
capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99
of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2
bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension
that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4
amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
