说明：  The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

参考文献“基于LLE的特征提取及应用”中的方法，我自己编写的一个LLE的测试数据处理方法程序。主要是针对新进数据如何进行LLE降维，配合matlab 降维工具箱Dimensionality Reduction v0.3b 使用。如有问题请指正。(It s a algorithm used to deal with new sample sets with LLE.)

本程序仿真了16QAM信号的载波相偏估计的HOS算法，整个算法实现分为（1）模拟发送端发送16QAM信号；（2）加入相偏来模拟通过信道后有相偏的测试信号；（3）利用HOS算法进行相偏估计与纠正；（4）输出星座图。(This procedure simulated a 16QAM signal carrier phase offset estimate of the HOS algorithm, the algorithm is divided into (1) analog transmitter to send 16QAM signal (2) by the inclusion of partial to simulate the channel after the phase offset of the test signal (3 ) algorithm using HOS phase offset estimate and correction (4) output constellation.)
