 利用fft()进行快速傅立叶变换，得到频谱，画出正弦函数及其频谱  找出频谱中使得Y轴取最大值时的估计频率记为ft  加入白噪声，绘出信噪比和均方误差的关系曲线 ( using fft () for fast Fourier transformation, spectrum, to draw the sine function and its spectrum  find the spectrum makes the Y-axis maximum value when the estimated frequency is denoted by ft  adding white noise, SNR plot and mean square error curve)

ofdm 解调simulink模块，调试版(OFDM demodulation simulink module, debug version)

说明：  由于飞机设计是一个需要多次反复迭代的重复过程，需要进行大量的计算，因此我自己编写了一些MATLAB程序(As the aircraft design is a need to repeat many times iterative process, requiring a large number of calculations, so I wrote some MATLAB program)

用于视频水印的攻击实验以及实验结果。通用攻击。(For video watermarking attacks, and experimental results. General attack.)

用matlab语言编的RF算法，有注释。RF算法一种性能较好的force-directed算法用来visualize small network(RF algorithm is one type of force-directed algorithm that is used to realize the small network visualization.)

pid算法原理解释，对初入学习PID的同学有很大帮助(pid algorithm principle explanation for entering the learning of the students are very helpful PID)
