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

在VC++6.0中用MSComm控件编程，可以实现串口接收数据和发送数据，数据分别显示在接收框和发送框中。 如何建立工程：建立新文件夹，将文档用WINZIP解压后，双击 Scommtest.dsw 即可在VC6.0中打开工程文件。作者主页上有详细编程说明，每一步都列出来了，可以参考。-In VC++ 6.0 using MSComm control programming, you can realize the serial receive data and send data, data were displayed on the receiver box and sent box. How do I create a project: create a new folder, and will extract the files using WINZIP, double-click Scommtest.dsw can open in VC6.0 project file. Author home page has a detailed program description, list each step, and can refer to.

数字调制技术一套的基础功能选择特定的调制方案。一般的基础功能是互相正交的。可以使用 "克施密特正交化" 过程派生的基础功能。一旦选择了基础功能，任何信号空间中的向量可以表示为基函数的线性组合。 在正交相移键控 （QPSK） 两个正弦波 (sin 和 cos） 作为基函数调制的。调制被通过不同相的基础功能，根据消息符号。在 QPSK，调制是基础，在那里有一个符号包含 2 位的象征。
