说明：  改进的DV-Hop定位算法matlab仿真代码 毕设的同学能弄用(Improved DV-Hop positioning algorithm matlab simulation code for the students to complete can get used to )

在理想环境下对ofdm进行仿真，有qpsk映射，ifft，d/a的转换，和接受等(In an ideal environment for simulation of ofdm, there qpsk mapping, ifft, d/a conversion, and acceptance of such)

用于在MATLAB中绘制多坐标轴，将多个变量绘制在一张图中(MATLAB is used to draw multiple axes, multiple variables are plotted in a graph)

说明：  通信系统中的定时同步仿真，经过matlab调试和编译，可实现定时信息提取和误差估计检测！！(Timing synchronization in communication systems simulation, debug and compile through matlab, timing information can be extracted to achieve detection and error estimates! !)

Essential tips for Matlab Programing

Harris采用了一种新的角点判定方法。矩阵M的两个特征向量l1和l2与矩阵M的主曲率成正比。Harris利用l1, l2来表征变化最快和最慢的两个方向.若两个都很大就是角点,一个大一个小就是边缘,两个都小就是在变化缓慢的图像区域.(Harris adopted a new method of determining the corner. Matrix M of two feature vectors l1 and l2 with the matrix M is proportional to the principal curvatures. Harris use l1, l2 to characterize changes in the fastest and slowest in two directions. If both are great that corner, a little is a big edge, both small change is slow in the image area.)
