SIM卡为表示能够执行proactive command且支持SAT，它必须在文件EFphaseTKG EFsst中有相关数据。 Phase文件指的是SIM卡所支持的GSM标准的级数，值为3则指SIM卡支持GSM phase 2和设置下传功能（profile download)。SST文件包含支持哪些GSM性能的准确信息。(SIM card that can support the implementation of proactive command and the SAT, it must file EFphaseTKG EFsst have relevant data. Phase document refers to the SIM card supports the GSM standard series, a value of 3 means the SIM card supports the GSM phase 2 and settings transfer function (profile download). SST file which contains support for GSM performance of accurate information.)

关于超宽带无线电基础的介绍以及相关代码，内容详细，通俗易懂，可供大家使用，互相学习。(On the introduction of ultra-wideband radio base and related code, detailed, easy to understand for everyone to use, learn from each other.)

华为GTM900AT命令手册，对开发GPRS具有指导意义(Huawei GTM900 AT command manual，It has a guiding significance to develop GPRS )

这是一篇现代通信原理课程的作业报告.题目为几种时频分析方法比较及应用.详细介绍了短时傅里叶变换、小波变换、魏格纳—威利分布和Cohen类时频分布这4种典型时频分析方法,并作了比较(This is a modern communication Principle operating report. Entitled Comparison of several time-frequency analysis and 应用. 详细 Jieshao the short time Fourier transform, wavelet transform, Wigner- Willie distribution and frequency distribution of Cohen Lei This four kinds of typical time-frequency analysis method, and compared)

主要是实现调制识别，区分几种常用的数字调制信号。含有两个文件夹 其一为特征参数的仿真；其二为正确识别率的仿真。文件夹key feature simulink中： 运行程序会得到各特征参数之间区分图 从图中可看到特征参数的有效性，见图。 文件夹classification rate simulink中：运行main.m文件 可以得到正确识别率 见图。(It is mainly to realize modulation recognition and distinguish several commonly used digital modulation signals. The simulation of two folders is one of the characteristic parameters, and the second is the simulation of the correct recognition rate. In the folder key feature Simulink: The running program will get the validity of the feature parameters that can be seen from the diagram, as shown in the diagram. Folder classification rate Simulink: running the main.m file can get the correct recognition rate.)
