移动通信基本知识:从通信网的角度看，移动网可以看成是有线通信网的延伸，它由无线和有线两部分组成。无线部分提供用户终端的接入，利用有限的频率资源在空中可靠地传送话音和数据；有线部分完成网络功能，包括交换、用户管理、漫游、鉴权等，构成公众陆地移动通信网PLMN。从陆地移动通信的具体实现形式来分主要有模拟移动通信和数字移动通信这两部种。-Basic knowledge of mobile communications: From the perspective of communication networks, mobile networks can be seen as an extension of wired communication network, which is both wireless and wired components. Part of user terminals to provide wireless access, frequency of use of limited resources in the air and reliable transmission of voice and data wired part of the completion of network functions, including switching, subscriber management, roaming, authentication and so on, constitute a public land mobile communication network PLMN. From land-based mobile communications to the specific forms of the main points have analog and digital mobile communications that two kinds of mobile communication.

The AsyncIO sample (also called the "PDC" sample) is a character-mode program for searching the files in a directory tree for a match against a pattern. It uses multiple threads, with each thread processing one file at a time, accumulating its matches. When each thread finishes searching a file, the thread sends the matches contiguously to a standard output.

pracsim是一个由仿真模型和可互连的仿真结构组成的模块集，为用户提供一个可修改及开发的基础模型，其他为附属文件。-pracsim is a simulation model and the simulation of interconnection structure of the module set, to provide users with a revised and the development of the model, other subsidiary documents.

 该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。     该程序也可以作为学习Matlab 通信仿真的入门实例
