正弦光栅,通过这个程序，可以长生一个纵向的饿512*512的正弦光栅，并通过图像显示出来(a sin grating and it could be showned trough the matlab program)

说明：  在QPSK调制方式下，高斯瑞丽信道，对MIMO系统的误码率性能仿真，简单易懂，可以得出误码率曲线(In QPSK modulation, the Gaussian Rui Lixin Road, on the BER performance of MIMO system simulation, easy to understand, bit error rate curve can be drawn)

This model were build to simulate flicker when switches the big load to the network. The result show that, when switches the load, voltage and current fluctuate and make flicker.

The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting the data of measurement for a given site. In a context of theoretical modeling, the profile of wind must satisfy two criteria: 1) The duration of the profile must be limited to reduce the time of simulation 2) The profile of the wind must be representative of the characteristics of the deposit (intensity, variability, statistical distribution…). In this study, we represented the evolution the speed of the wind, by a scalar function which evolves/moves in time, modelized in deterministic form by a sum of several harmonics. Profile of the wind simulated with a mean velocity of 8.2m/s.
