数字通信第四版答案。 对学习数字通信的同学比较有用。(the answer of digital signal communication)

说明：  在simulink环境中搭建的风力机模型，能够输出风力机的功率和转矩曲线(Built environment in the simulink model of wind turbine, wind turbine output to the power and torque curves)

结合混沌搜索的进化算法，利用logistic混沌映射与进化算法的结合解决问题(Logistic chaotic improvements)

采用M2M4信噪比估计算法对QPSK调制解调器的接收端信噪比进行了估计(M2M4 SNR estimation algorithm on the the QPSK modem receiving end signal-to-noise ratio estimated)

说明：  捷联惯导系统放置在室内测试台上做静态测试，测试时间4500s。 1）取前180数据做粗对准（解析对准法）； 2）取第181s~900s数据做精对准（Kalman滤波法）； 3）从第901s开始做纯惯导解算； 4）用国军标的导航系统位置精度评价方法评估系统定位精度（分别计算CEP50 和 CEP95 下的定位精度）。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s. 1) take the first 180 data for rough alignment (analytical alignment method); 2) accurate alignment of 181s-900s data (Kalman filtering method); 3) pure inertial navigation solution is performed from 901s; 4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)

some soucre code for clustering

说明：  扩展卡尔曼滤波器程序，只需改相关参数即可(Extended Kalman filter process)

this is for ofdma application

EKFUKF工具箱,卡尔曼滤波工具箱，很不错的(EKFUKF toolbox, Kalman filter toolbox, very good)
