说明：  sr 随机过程 变换 图形显示 动画显示 帮助理解(sr stochastic ronence picture show help to understand sr)

说明：  供大家学习UWB的simulink建模,希望大家多多交流(UWB for them to learn the simulink model, I hope things to share)

this simulink is for automatic pilot control using PID controller

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

学进一步了解分类器的设计概念，能够根据自己的设计对线性分类器有更深刻地认识，理解Fisher准则方法确定最佳线性分界面方法的原理，以及Lagrande乘子求解的原理。(school with a better understanding of classification of the design concept, According to the design of linear classification for a more profound understanding, Fisher understood the criteria to determine the best method of linear interface of the theory, Lagrande and multiplier for the principle.)
