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

这是一个实现linux系统下的scp的命令相同功能的程序，客户端和服务端通信使用了自己定义了的通信协议。
文件传送协议格式：
服务器路径#服务器上的文件名#操作类型#文件大小
操作类型：0代表上传操作 1代表下载操作
文件大小：上传下载的文件大小
服务器返回的消息类型：
0 ：服务器创建文件失败
1：服务器操作成功
2：文件大小不同 （未实现）
注意：
1:正则表达式没有实现
2:其余实现
3:服务器可以为多个客户端服务，用多进程实现-This is a linux system realize the scp command functions the same procedures, client and client communication services using its own definition of the communication protocol. File Transfer Protocol format: server path# Server 23 file name! Operation type# File size operation types: 0 From operated on behalf of one operation on behalf of download file size: From the size of the downloaded file to return to the news server type: 0 : The server failed to create file 1: Server operation successful 2: documents of different sizes (not realize) Note: 1: regular expression did not realize 2: the rest of the realization of 3: The server can service multiple clients, and realize multi-process
