Matlab仿真应用模型，仿真电力系统的各种故障类型，基于SIMULINK(Matlab simulation application model, simulation of various fault types of power system based on SIMULINK)

simulink下使用的关于通讯系统的实例，例如调制解调，看频谱，采样等。(simulink to use on an instance of communication systems, such as modulation and demodulation, see the spectrum, sampling and so on.)

At this moment, the major obstacle of wide PV system commercialization is the high initial investment cost that stems from the strict grid connection standards and high expectations from the PV system [2], [3]. The grid-connected PV system consists of two parts: PV arrays that convert irradiation to electrical energy, and the converter that feeds the energy into the grid.

MATLAB仿真，二进制调制信号（ASK,FSK,PSK）(MATLAB simulation , the binary modulation signal)

采用DIT和DIF两种蝶形算法实现的FFT变换，其中myfft1是DIT算法，myfft2是DIF算法，已经过测试，可以方便使用。(DIT and DIF using two algorithms of FFT butterfly transformation, which myfft1 is DIT algorithm, myfft2 is the DIF algorithm, has been tested, it will be convenient to use.)
