无迹卡尔曼滤波算法对经典的一维非线性系统仿真，有图有真相哦。(ukf，unscented kalman filter)

实现卡尔曼滤波功能，建立了一个对位置观测的系统，同时加入了速度噪声，完成了Matlab的仿真。(Kalman filtering, established a system of observation position, while adding speed noise, completed the Matlab simulation.)

汽车直线行驶工况分析，simulink模型，可自行修改参数(Automotive straight driving cycle analysis, simulink model, free to modify the parameters of)

如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )

X-band雷达仿真程序，等等等等，用于分析实际信号(X-band radar simulation program, and so on and so on, used to analyze the actual signal)

说明：  圆拟合，通过已知的多组数据，拟合出最小误差的圆(Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2)

MIMO方面一篇非常的文章，无线通信的，协同通信，中继选择的(MIMO an article, wireless communications, cooperative communication, the relay selection)

WiFi Direct直连，实现了直连，能正常检测链接，没问题(WiFi Direct Direct Connect, to achieve a straight, normal detection link, no problem)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元间距为入射信号波长的1／2，快拍数为200，信噪比为20dB，阵元数分别为10，50，100。 (Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element spacing of the incident signal wavelength of 1/2, the number of snapshots 200, SNR is 20dB, the array element number 50, 100, respectively.)
