一个直序/跳频混合式扩频通信系统的仿真

文件中包括的随机数发生器，将 Alist 矩阵转换成一般矩阵，做的 enc 部分。此 enc 方法只侧重于下三角矩阵，它可以变得更容易得到 enc 消息。希望此文件可以帮助您很多有关如何进行编码与低三角奇偶校验矩阵的 LDPC 码。我也写一个 matlab 文件来检测代码 c 是正确还是不。

在Android中对Wifi操作，android本身提供了一些有用的包，在android.net.wifi包下面。简单介绍一下： 大致可以分为四个主要的类ScanResul

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

Modbus协议规范,非常详细的文档,对编写协议软件有帮助-Modbus

该verilog 串口通信程序采用分层思想，主要由顶层模块、波特率发生器模块、数据发送模块和数据接收模块4个模块构成，功能划分明确，便于系统设计和调试。

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
