this code is one of our homework in image processing which belong to gonzales

msk调制，希望大家好好学习，天天向上，努力提高自己(msk modulation, I hope you study hard, every day, strive to improve their)

奇异值与主成分分析（PCA)的介绍,比较简明易懂,对初学人大有帮助(SVDAND PCA,HOPE TO HELP YOU,IF YOU HAVE SOME QUESTION ASK ME)

最优化 LM算法, 实现二次函数为目标函数的非线性优化(L-M Optimization method)

此程序用于OFDM与FBMC的对比，详细描述了UFMC系统的发送和接收的仿真实现过程，并对比相同系统参数下的OFDM系统，发现FBMC系统的优势。(This program is used for OFDM and FBMC contrast, describing the detail of UFMC transmitter and receiver simulation process, and comparing the the OFDM system under the same system parameters to verify the advantages of FBMC system.)

利用matlab平台，采用双线性变换法设计一个IIR数字高通滤波器。主要是运M语言编写的代码，已成功运行，滤波器的性能还不错。

小数据量法计算最大lyapunov指数工具箱，原来的那个工具箱中有点误差，现在改进了只对前一部分直线状数据进行计算，使结果更加准确(A small amount of data calculated index of the largest lyapunov toolbox, the original error that the toolbox a bit, and now has improved only in a straight line like the first part of the data is calculated so that the results more accurate)

实现了1D,2D,3D空间自由度下的运动参数的扩展Kalman滤波算法，文章2008 IROS Visual SLAM for 3D Large-Scale Seabed Acquisition Employing Underwater Vehicles的具体实现。(a novel technique to align partial 3D reconstructions of the seabed acquired by a stereo camera mounted on an autonomous underwater vehicle. Vehicle localization and seabed mapping is performed simultaneously by means of an Extended Kalman Filter. Passive landmarks are detected on the images and characterized considering 2D and 3D features. Landmarks are re-observed while the robot is navigating and data association becomes easier but robust. Once the survey is completed, vehicle trajectory is smoothed by a Rauch-Tung-Striebel filter obtaining an even better alignment of the 3D views and yet a large-scale acquisition of the seabed.)

利用matlab进行五点三次法平滑处理(时域和频域)(Using matlab 5.3 times France smoothing process (time domain and frequency domain))
