基于MATLAB/SIMULIN，搭建的光伏系统最大功率跟踪爬山法的定步长模型(Structures of the PV system based on MATLAB/SIMULIN, climbing method of maximum power point tracking fixed step model)

一维标准的WENO程序，使用了matlab编程环境。(standard one dimensional code of weno scheme using matlab.)

这是我搭建的10W小功率太阳能电池模型，可根据实际情修改太阳能光伏电池的功率、短路电流、开路电压、额定电流和额定电压。另外还有最大功率跟踪模型和高频升压逆变模型也传上来，做得比较简单，有需要的可以参考一下~(Solar photovoltaic power generation system)

介绍了matlab与vc的接口编程，并引入了常见问题解决。(Introduces MATLAB and VC programming interface, and introduces common problems)

双DQ锁相PLL算法的研究，具有一定参考价值。(Research Documentation double DQ phase-locked PLL algorithm has some reference value.)

QPSK modulation in Rayleigh channel

Audio signal modelling containing a sequence of 2 identical chirp signals with an addition to filtering an image using simple low-pass 1-D filter.

本程序是牛顿拉夫逊法求解电力系统潮流计算，包括节点导纳矩阵的计算等(This program is the Newton Raphson method for solving power flow calculation, including the calculation of the node admittance matrix, etc.)

LMS滤波，自适应滤波法，试过了，可以用(LMS filter, adaptive filtering, tried, you can use)

读取星历观测文件GPS和北斗卫星的可见卫星数作为输出(read ephemeris observation file to give out GPS and Beidou visible satellite number)
