说明：  MATLAB时频分析工具箱,很红用，很好用，行了吧。靠。(tftb mmmmmmmmmmmmm)

主程序产生一个稀疏信号调用子程序进行迭代重建(Main program calls subroutine to generate a sparse iterative signal reconstruction)

There is a code for spectrum sensing..in this code roc curve is generated..

说明：  VMD是通过迭代搜寻变分模型（具体怎么搜寻，请亲们自己看，我主要讲他的大概）最优解， 来确定我们所知的模态uk(t)及其对应的中心频率ωk和带宽。 每个模态都是具有中心频率的有限带宽（就是在频域中有在一定的宽度）。所有模态之和为源信号。(VMD is to determine the modal UK (t) and its corresponding central frequency, k and bandwidth by iteratively searching for the optimal solution of the variational model (see dear friends for details, and I will mainly talk about his approximate solution). Each mode is a finite bandwidth with a central frequency (that is, a certain width in the frequency domain).The sum of all modes is the source signal.)

稀疏均匀圆阵求根MUSIC算法,包含波束空间变换，映射及求跟MUSIC算法的实现(Solving sparse MUSIC algorithm for uniform circular array, including the beam-space transformation, mapping, and seek to achieve with the MUSIC algorithm)

用MATLAB对ofdm系统的性能仿真，比较不同的多径数对系统性能的影响(MATLAB right ofdm the performance of the system simulation, comparing different multi-track system performance on a number of)

F16开环动力学模型，采用C语言编写的MATLAB S函数。输入为油门及3个舵面共四个控制量，以及系统低阶、高阶选择器。前缘襟翼模型内部自动调节。输出为12个状态量以及油门大小。采用欧拉角坐标系。(F16 open-loop dynamic model, using the C language MATLAB S function. Throttle input, and three of four rudder control volume, and system low, high selector. Automatically adjust the front flap inside the model. The amount of output for the 12 states and the accelerator size. Using Euler angle coordinate system.)

自己编写的程序，能够实现单变量的线性回归，随机产生训练样本，利用梯度下降法实现训练过程，并且画出了误差的迭代曲线。(I have written a program that can achieve single-variable linear regression, random training sample using gradient descent method to achieve the training process, and draw the iterative curve errors.)
