SVG多边形图片网格布局代码特效是一款通过SVG来将屏幕划分为多个多边形，每个多边形中设置一张背景图片。(SVG Polygon Picture Grid Layout Code is a special effect that divides the screen into multiple polygons through SVG, and sets a background picture in each polygon.)

说明：  在车载网络中，尤其是在城市环境下，车辆高速移动导致网络拓扑结构频繁变化，车辆密度分布不均，导致稀疏连通和局部最优情况频繁出现，所以必须专门为车载自组网设计具备鲁棒性、可靠性、实时性的路由协议。本章针对现有城市环境下存在的车辆碰撞问题，利用车辆的地理位置和电子导航地图提供的道路车流信息进行路由决策，根据设定的城市交通网络模拟图，随机的分布车辆节点，通过十字交叉路口的防碰撞研究以及路边节点之间的相对位置预警仿真，得到不同仿真下的城市交通信息网络结果图，对于该区域交通通信设计以及路况信息改善有一定的指导意义(In the vehicular network, especially in the urban environment, the high-speed movement of vehicles leads to frequent changes in network topology and uneven distribution of vehicle density, which leads to the frequent occurrence of sparse connectivity and local optimization. Therefore, it is necessary to design a routing protocol with robustness, reliability and real-time for vehicular ad hoc networks. Aiming at the problem of vehicle collision in the existing urban environment, this chapter uses the geographic location of the vehicle and the road traffic flow information provided by the electronic navigation map to make routing decisions. According to the set urban traffic network simulation diagram, the vehicle nodes are randomly distributed.)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.
