西安电子科技大学精品课程——数字信号处理.《数字信号处理教程——MATLAB释义与实现》 本教程系统地讲解了数字信号处理的基本理论和方法，注重物理概念的阐述，尽量把MATLAB的多媒体功能用于图形、动画和声音等形象的演示，是一本自始至终使用MATLAB来阐述问题和进行计算的数字信号处理教材。(Xi' an University of Electronic Science and Technology Courses- digital signal processing. " Digital signal processing tutorial- MATLAB interpretation and implementation" of the tutorial system to explain the basic theory and methods of digital signal processing, focusing on elaborate physical concepts, try to MATLAB multimedia functions for graphics, animation and sound, and image presentation, is a problem throughout to illustrate the use of MATLAB to calculate and digital signal processing materials.)

船舶AIS轨迹提取，作出船舶AIS轨迹图。在此基础上，实现基于空间相似距离的K均值轨迹聚类。算法可以自定义轨迹聚类初始轨迹或者由程序随机生成初始轨迹，采用迭代的方法直到确定最终的聚类中心。(The extraction of ship AIS trajectory, make ship AIS trajectories. On this basis, to achieve similar K mean trajectory clustering based on distance space. You can customize the initial trajectory trajectory clustering algorithm or randomly generated by the program initial trajectory, iterative method was used to determine the cluster center until the end. )

用于一般访求不能达到分辨率的频率检测方法，可以高精度检测频率。尤其是对于分辨率达不到要求的时候，用此方法能达到很高的分辨率。对有用频段的频率进行高分辨率的细化。(Usually visit requirements can not achieve the resolution of the frequency detection methods, and can be detected with high precision frequency. Especially for the resolution of failing to meet required when using this method can achieve high resolution. Useful frequency band high-resolution refinement.)
