变流器的预测控制，模型搭建成功，仿真结果符合要求。(Converter predictive control, built a successful model, the simulation results meet the requirements.)

这是TVAL3算法，是基于增广拉格朗日法和交替方向法的全变分最小化算法。这个算法是有关压缩感知的重建算法的例子。TVAL3算法是在最小全变分法的基础上，结合了增强型拉格朗日函数和交替最小化方法。通过交替最小化方法寻找增强型拉格朗日模型的最小值，再由最速下降法进行迭代，更新拉格朗日乘子。 (TVAL3: TV minimization by Augmented Lagrangian and ALternating direction ALgorithms.This algorithm is an example of a reconstruction algorithm for compressed sensing. The TVAL3 algorithm is based on the minimum total variation method, which combines the enhanced Lagrange function and the alternating minimization method. The minimum value of the enhanced Lagrange model is sought by the alternate minimization method, and then the iterative method is updated by the steepest descent method.)

RS码的matlabb仿真非常有帮助的东西，完整源代码。 (RS code matlabb simulation is very helpful things, complete source code.)

对信号进行频谱分析及滤波，虚拟力的无线传感网络覆盖，仿真效果非常好，具有丰富的参数选项,本程序的性能已经超过其他算法，DC-DC部分采用定功率单环控制。

说明：  GPS信号频谱，matlab语言，里面有CA码和P码的子文件，最后将各信号频谱画出来。(GPS signal spectrum, MATLAB language, there are ca code and P code sub file, finally the signal spectrum will be drawn.)
