带有MPPT功能的光伏阵列Matlab通用仿真模型(Versatile Matlab Simulation Model for Photovoltaic Array with MPPT Function)

基于最小二乘算法（RLS)的回波消除，直接可以运行(Based on least squares algorithm (RLS) of echo cancellation can be run directly)

we investigate a new blind adaptive fractionally-spaced TEQ (FS-TEQ) for multicarrier systems in order to reduce efficiently intersymbol interference. We also exploit the cyclic prefix and fractionally-spaced TEQ to create a blind adaptive globally convergent channel-shortening algorithm.

将信号用小波函数SYM5分解到第5层，用minimaxi阈值选择对系数进行处理，消除噪声(SYM5 decomposition using the wavelet function signals to the fifth floor, use minimaxi threshold choice to deal with coefficient, eliminate noise)

说明：   有一个长度为整数L(1<=L<=10000)的马路，可以想象成数轴上长度为L的一个线段，起点是坐标原点，在每个整数坐标点有一棵树，即在0,1,2，...，L共L+1个位置上有L+1棵树。 现在要移走一些树，移走的树的区间用一对数字表示，如 100 200表示移走从100到200之间（包括端点）所有的树。 可能有M(1<=M<=100)个区间，区间之间可能有重叠。现在要求移走所有区间的树之后剩下的树的个数。 输入： 两个整数L(1<=L<=10000)和M(1<=M<=100)。 接下来有M组整数，每组有一对数字。 输出： 可能有多组输入数据，对于每组输入数据，输出一个数，表示移走所有区间的树之后剩下的树的个数。(Has a length of integer L (1 &lt = L &lt = 10000) of the road, one can imagine a number line segment of length L, the starting point is the coordinate origin, each integer coordinate points in a tree, i.e. 0,1 , 2, ..., L total has L+1 L+1 positions on the tree. Now to remove some trees, tree removed by a range of digitally represented, such as 100 200 represents removed (inclusive) between 100 and 200 all the trees. There may be M (1 &lt = M &lt = 100) intervals, there may be overlap between the intervals. Now, after the number of trees require the removal of all remaining sections of the tree. Input: two integer L (1 &lt = L &lt = 10000) and M (1 &lt = M &lt = 100). Then there is an integer M groups, each with a pair of numbers. Output: there may be multiple sets of input data, for each set of input data, the output of a number indicating the number of the removal of all remaining sections of the tree after tree.)
