介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型-Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model

用C及ftp实现软件自动升级。通过在服务器端建立FTP服务,实现远程主机的文件更新. 软件启动过程连接服务器,获得软件文件更新列表(此步省略),进行本地文件更新 启动过程进行系统调用执行批处理文件ftpget.bat,调用方式system( "e:ftpget.bat" ) 文件ftpget.bat负责连接服务器下载所需文件,并完成文件的更新-C ftp software and automatic upgrades. Through the establishment of FTP server, remote mainframe file updates. Software startup process server connectivity, access to software updates list (this step is optional), a local paper started the process of updating system calls for the implementation of batch file ftpget.bat, call mode system ( "e : ftpget.bat") documents ftpget.bat for connecting servers to download the necessary documents, and complete the document update
