ABAQUS-UMAT-paper

这是一个关于预失真模型的matlab程序，同时里面结合了延时估计算法。(this is a matlab program about the model of digital predistorter,and uesed with the delay estimation algorithm.)

1.数据时随机产生的（产生1000个随机数），进行排序2.每一次数据排序之后，都可以看到排序的移动，交换次数以及排序的时间。 (1. After randomly generated data (generated 1000 random numbers), every sort 2. Sort the data, you can see the sort of move, switching times and sort of time.)

电力系统连续潮流计算，以牛拉法潮流计算为基础，用来求解系统的PV曲线。(Continuous power system load flow calculation, using bovine Rafah flow calculation, based on the system used to solve the PV curve.)

说明：  基于CORDIC算法计算反正切函数。输入横坐标纵坐标及迭代次数，输出角度及弧度值；附CORDIC英文文档说明(atan function based in CORDIC algorithm)

该算法，先对协方差矩阵进行休整，然后用信息论的方法得出信号的源数，这是进行空间普估计的基础(The algorithm, first on the covariance matrix for a rest, and then used information theory methods to draw a number of signal sources, it is estimated that the basis of space S )

采用QR分解方法计算矩阵特征值和特征向量(computes a partial Schur decomposition of a square matrix or operator)

kriging方法源程序，用于kriging方法构建近似模型，方便易懂(kriging method source，Kriging method used to construct an approximate model, easy to understand)

sap4源代码！by fortran 这是一个有限元计算的软件 可以完成平面，三维的计算功能(SAP4 source code! By FORTRAN This is a finite element software can be completed planar, 3D computing power)

说明：  恒模算法的简介，它适用于信道的盲均衡。Matlab程序提供基本的框架，可以修该里面的参数以测试该算法的性能(CMA briefings, which applies to Channel Blind balanced. Matlab to provide a basic framework, it can be done inside of the parameters to test the performance of the algorithm)

三次样条曲线拟合代码，先训练，后差值，计算非常准确(Three times spline curve fitting, the first training, and after, computation is very accurate)
