神经网络模型权重系数判定用的代码，back propagation(Code neural network model of weight coefficient determination, back propagation)

主要针对 MIMO中的alamouti 进行仿真测试，有2发1收，3发1收，4发1收 进行比较。(Mainly for the alamouti MIMO simulation test, there are two hair a close, 3 rounds a close, four made a close comparison.)

通过对OFDM信号的CCDF曲线进行分析，得出了联合哈特莱变换和限幅算法降低OFDM信号峰均比的方法确实降低了OFDM信号的PAPR值(through the analysis of CCDF curve of OFDM signal, it is true to reduce the PAPR value of OFDM signal by use the method of the United Hart transform and clipping algorithm for PAPR reduction)

迭代加权最小二乘法（IRLS），用以恢复压缩采样后的信号(Iteratively Reweighted Least Squares Minimizaion for Sparse Recovery)

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).)
