本文根据移动通信衰落信道的工作机理, 基于加性高斯白噪声信道( AWGNChannel) 、 落信道( RayleighFading Channel) 、莱斯衰落 icianFadingChannel) 的仿真模型, 并利用M 行了衰落信道的误比特率性能的仿真分析。(Based the working mechanism of the mobile communications fading channel, Based on the additive white Gaussian noise channel (AWGNChannel), The down channel (RayleighFading Channel), Rice fading icianFadingChannel) simulation model, and the use of M Line simulation analysis of the the fading channel bit error rate performance.)

主要讲解了航空信道模型的仿真实现和参数选择，给出了各信道场景下的接收信号星座图以及概率密度曲线。(Mainly on the aviation simulation channel model implementation and parameter selection are given scenarios each channel received signal constellation and the probability density curve.)

主要是基于mtlab的程序，MinkowskiMethod算法 ,matlab实现了五类灰色关联度模型的计算。( Mainly based on the mtlab procedures, MinkowskiMethod algorithm, matlab implements five gray correlation degree computing model.)

说明：  通过几个图文示例，详细说明了如何在matlab上通过虚拟串口发送和接受数据(Through a few graphic examples, detailed description of how to send and receive data through virtual serial port on matlab)

类似simulink的小程序，在网上找到的，希望对大家有用。。(Similar simulink small program, found on the Internet, we want to be useful. .)

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.)

可以得到很精确的幅值、频率、相位估计，基于K均值的PSO聚类算法,光纤陀螺输出误差的allan方差分析。( You can get a very accurate amplitude, frequency, phase estimation, K-means clustering algorithm based on the PSO, allan FOG output error variance analysis.)
