a code for seismology Inversion

this is watermark source code. it is good for making programming

create a gaussian bell

projection and backprojection

基于密度的聚类算法，DBSCAN算法，在Matlab上实现。文档中包含两个txt的数据集，读者可替换数据集感受DBScan算法聚类的实现结果。

说明：  3GPP LTE中上行虚拟MIMO比例公平调度算法的源程序代码(Virtual MIMO in 3GPP LTE uplink proportional fair scheduling algorithm source code)

此程序为局部线性嵌入，能够实现降维功能。(This program is locally linear embedding and can realize dimensionality reduction function.)

说明：  采用继电法对PID参数进行整定，实现PID参数的获得(Method using relay tuning PID parameters, PID parameters to achieve access to)

IEEE 802.11a系统OFDM仿真。假设OFDM系统物理层采用802.11a系统物理层参数，其中，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径瑞丽衰落信道，接收端采用理想信道估计和利用训练符号进行信道估计时的误比特性能(IEEE 802.11a system OFDM simulation Assuming that the OFDM system physical layer uses the 802.11a physical layer parameters, among them, 1 long training symbols and 6 OFDM data symbol consisted of 1 frames, the channel into a single path Ruili fading channel, the receiver uses the ideal channel estimation and utilizes the training symbols to estimate channel bit error performance of the)

说明：  虚拟同步机孤岛模型，已经调好参数，图形正确，可供学习(Island model of virtual synchronous machine)

该项目是关于视频稳定手持或通过安全摄像机捕获视频有太多的噪音和生涩，因此，我们的项目是用来去除噪声和做更稳定的视频。
