数字水印的傅里叶算法，大学本科论文，图像处理，信息安全等。(Fourier transform algorithm of the digital watermark, undergraduate thesis, image processing, information security.)

信号分为同相信号和正交信号，分别进行正交采样，降低采样率，搬移频带，完成采样。(Signal into in-phase signal and the quadrature signal, respectively, quadrature sampling, the sampling rate decrease, moving band, complete sampling.)

将任意格式图片转换成24位的mif文件，应用于FPGA中的VGA显示，非常好用哦！！！(Any format images converted into 24 MIF files, used in VGA FPGA display, very good with oh!!!)

说明：  计算掘进机横摆工况截割头合力，并绘制合力曲线(Calculated yaw conditions TBM cutting head together)

transformator simulation

顺便附上几张仿真图 这是状态图 要注意的是：必须把系统状态和kalman滤波器内部预测的状态分开(Incidentally, several simulation map attached to this is the state diagram should be noted that: must be the system state and kalman filter to separate the state of internal forecasts)

本源代码主要实现谐波小波的分解及重构的matlab程序。(Source code of the main harmonic wavelet decomposition and reconstruction of the matlab program.)

基于matlab的机器人路径规划源代码。。。。。。(The robot path planning based on matlab source code. . . . . .)

跳频码性能分析，自相关函数的实现，据此可以分析跳频码的优劣( AHanming is the auto correction)

（1） 熟悉连续信号经理想采样前后的频谱变化关系，加深对时域采样定理的理解． （2） 熟悉时域离散系统的时域特性 （3） 利用卷积方法观察分析系统的时域特性． （4） 掌握序列傅立叶变换的计算机实现方法，利用序列的傅立叶变换对连续信号，离散信号及系统响应进行频域分析． ((1) familiar with the continuous signal to the manager before and after the sampling of the spectrum changes relations and deepen the time-domain sampling theorem understanding. (2) familiar with the time-domain system discrete time-domain (3) using deconvolution method of analysis in time domain characteristics. (4) master sequence Fourier Transform computer, using the Fourier transform sequence of continuous signals, Discrete signal system response and frequency domain analysis.)
