two_D_FFT

简单的OFDM仿真，采用QPSK调制，有串并转换，保护间隔，fft/ifft等(Simple OFDM simulation using QPSK modulation, there are serial to parallel conversion, guard interval, fft/ifft etc.)

matlab实现PVD方法和基于模函数PVD的方法，自己写的，图像隐写的研究内容(matlab implementation PVD PVD method and the method based on mode function, write, and images of the contents of steganography)

内有多个m文件！希望能帮助到有需要的朋友！其中有几个关于lms的m文件！(m with a number of documents! Hope can help to the needy friends! While a few of the LMS m documents!)

pi/4-dqpsk 调制解调 的 matlab 仿真，通过srrc滤波器实现16倍的上采样(pi/4-dqpsk modulation and demodulation matlab simulation, through srrc filter to achieve 16 times the sampling)

该段代码可用于加速度信号的积分求得位移。使用的是频域积分方法，设置合适的上下限截止频率可较好的复现实际路面的位移高程。(This code can be used for integration of the acceleration signal obtained displacement. Using a frequency-domain integral method, set the appropriate upper and lower cutoff frequency displacement elevation better reproduce the actual road.)

程序里面有renix格式的数据，可以用来进行进行精密单点定位处理。(The program has data in renix format, which can be used for precise point positioning)
