跳时超宽带信号的产生，（本代码调试通过）(UWB signal generation)

说明：  自己写的算术编码的matlab程序,内容是把自己的名字(当然也可以是其他的文字)用算术编码编码后再解码,有详细注释.给初学编码的朋友一些参考.谢谢.(Write matlab arithmetic coding procedure is to divide his name (of course also be other text) and then decode encoded using arithmetic coding, a detailed comment. Beginners encoding a friend to some reference. Thank you.)

数字信号处理基础.比较适合初学者，内容详尽，有不少高校用作教科书。(Based on digital signal processing. More suitable for beginners, detailed, many universities as textbooks.)

自己写的一个计算空间时频分布的程序，魏格纳威尔分布原代码(Wrote a frequency distribution calculating space program, Wigner distribution of the original code Weir)

粒子群算法，也称粒子群优化算法（Particle Swarm Optimization），缩写为 PSO， 是近年来发展起来的一种新的进化算法(（Evolu2tionary Algorithm - EA）。PSO 算法属于进化算法的一种，和遗传算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。(Particle swarm optimization, also known as particle swarm optimization (Particle Swarm Optimization), abbreviated as PSO, is a new evolutionary algorithm developed in recent years ((Evolu2tionary Algorithm- EA) .PSO algorithm is an evolutionary algorithm, and similar genetic algorithm, it is also starting random solutions, through iterative search for the optimal solution, which is also uated by the quality of the fitness solution, but it is much simpler than genetic algorithms rule, it does not have the genetic algorithm cross (Crossover) and variant (Mutation) operation, which by following the current search to find the optimal value to the global optimum. the algorithm for its easy implementation, high accuracy, and fast convergence advantages attracted academic attention, and in solving practical problems demonstrated its superiority.)

matlab模糊数学工具箱，包含常见的模糊聚类，模糊预测等，期待和大家一起分享。(The matlab fuzzy toolbox, including common fuzzy clustering, fuzzy prediction, etc., looking forward to share.)

说明：  充分理解傅立叶变换，直接根据傅立叶积分公式编写，并显示单边，双边谱，对于理解单双边频谱有一定帮助。本程序通过函数与调用来呈现。(Fully understand the Fourier transform, Fourier integral formula directly in accordance with the preparation, and display the unilateral, bilateral spectrum, the spectrum for the understanding of a certain single bilateral help. This procedure with the call to a function.)

该程序能通过加标签将模拟表盘得刻度删除掉！通过大量得图片都能得到很好得效果！(through the process of labeling analog dial in the calibration deleted! Through a picture can be a very good result!)

模式识别课件，神经网络，支持向量机，内容很经典(Courseware pattern recognition, neural networks, support vector machine, which is very classic)
