PID-DTC

关于对hvx人体视觉水印的编写。有小波水印的全过程：分解、嵌入、重构、提取。人体视觉的体现：三大重要系数的利用 (On the preparation of hvx human visual watermark. There wavelet watermark the entire process: decomposition, embedding, reconstruction, extraction. Human visual manifestation: the use of three most important factors)

基于阶跃响应的专家控制器，并使用matlab编写的m文件进行仿真(Based on the step response of the expert controller, and use the preparation of the m file matlab simulation)

压缩文件里边包含好几个合成地震记录的程序，包括楔形模型，断层等，有的还画出了地震记录，反射系数的振幅谱~(the zip file contains several synthetic seismogram programs, including wedge model, fault model, etc., some even draw the earthquake records, the reflection coefficient of amplitude spectrum ~ )

OFDM的代码和模型，关于QAM和QPSK调制，两个都有哦，适合初学者学习(OFDM code and model, on QAM and QPSK modulation, two have, oh, suitable for beginners to learn)

PID Tunning with PSO

结合雷达跟踪的空中目标的实际情况，针对目标运动模型中的线性运动和非线性运动，分别设计了两种模型，并用马尔科夫状态转移矩阵实现IMM算法。最后对交互多模型卡尔曼滤波算法进行了Matlab仿真及结果分析。(Combined with radar tracking air targets, for linear and non-linear movement of target motion model, two models were designed and used a Markov state transition matrix IMM algorithm. Finally, the interacting multiple model Kalman filter algorithm Matlab simulation and results analysis.)

将从地震勘探工程标准格式的segy文件读出的数据重新写成segy格式，方便用专业的软件进行继续处理。(Reading data seismic engineering standards segy file formats out of the rewritten segy format, easy to use specialized software to continue processing.)

张正友标定算法的matlab程序实现摄像机的内外参数的标定(Zhang Zhengyou calibration algorithm matlab program)

matlab下用FFT求功率谱和幅值谱的代码(Power spectrum and Amplitude spectrum base on matlab)

有噪声心电图和滤除噪声的心电图，对初学者来说有个大概的认识。(ECG noise ECG and filter out the noise, probably for beginners.)
