fit_ellipse - finds the best fit to an ellipse for the given set of points.(fit_ellipse- finds the best fit to an ellipse for the given set of points.)

matlab上广泛流行的绘制地图和流线图的m_map插件工具箱。加入该插件可以让matlab直接进行绘制地图(The code for map contouring in the matlab)

主要用MATLAB对图像惊进行处理，对图像进行直方图处理 给出均衡前后的图形很有实用(Main MATLAB to image surprised processing, the image histogram equalization before and after the treatment given graphics is practical)

现代数字通信系统中的各种调制技术的和高斯白噪传输的matlab实现。(Modern digital communication systems in a variety of modulation techniques and transmission of Gaussian white noise matlab achieve.)

脊线提取是信号处理很重要的一个项内容 这里用MATLAB语言实现了脊线的提取 (Ridge extraction is a very important signal processing items here in MATLAB language to implement the extraction ridge)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

实现数据的频域分析，希望大家能提点宝贵意见，能共同进步，交流心得！！(The frequency-domain data analysis, we hope to be able to provide valuable advice points can progress together, exchange ideas! !)

we shed light on the potential and implementation of index modulation (IM) techniques for MIMO and multi-carrier communications systems which are expected to be two of the key technologies for 5G systems. Specifically, we focus on two promising applications of IM: spatial modulation (SM) and orthogonal frequency division multiplexing with IM (OFDM-IM), and we discuss the recent advances and future research directions in IM technologies towards spectral and energy-efficient 5G wireless networks.
