宽带DOA的TCT算法，从本网站下载之后，发现程序有点问题而不能运行，对线性调频信号的生成做了小改动后，程序可以正常运行(The TCT algorithm for broadband DOA，the code is download from this website previously, but find a problem and the program can t run , then modify the code of linear FM signals generation, the program can run)

Matlab入门级OFDM仿真 (Matlab entry-level OFDM simulation )

Matlab plot函数使用方法（详细）( Matlab plot function using method (detailed))

时窗长度与物理分辨率，频谱泄露之间的关系(The length of time windows with the physical resolution of the spectrum reveal the relationship between the)

说明：  QPSK（四进制相移键控）信号的产生及调制解调过程（经高斯和瑞利信道）的仿真(QPSK (quaternary phase shift keying) signal generation and modulation and demodulation process (by the Gaussian and Rayleigh channel) Simulation)

电动汽车的车轮simulink仿真模型，输入为汽车的横摆角速度、汽车纵向速度和汽车的横向速度，输出为汽车在汽车坐标系下的相应速度(Electric vehicles wheels simulink simulation model, enter the horizontal speed of the car' s yaw rate, vehicle longitudinal speed and the car output the corresponding speed of the vehicles in the car coordinate system)

图像处理MATLAB源代码，这个是贝叶斯估计-bayes guess(Image Processing MATLAB source code, this is the Bayesian estimation-bayes guess)

多址干扰一直是造成cdma系统容量限制的重要原因，本程序主要模拟了多址干扰对每个用户的影响以及把多址干扰作为高斯白噪声看待时对用户的影响(MAI has been caused CDMA system capacity limit of the important reasons the procedures simulated the MAI for each user to the effects of MAI as a Gaussian white noise when users view the impact)

通过比较传统仅移相的波束与移相+理想延时的波束，来说明述S波段宽带阵列孔径渡越现象(To demonstrate the aperture effct of S_band windband array, this programe comparing the beam pattern of the traditional beamforming method "phase shifting only" with that of "phase shifting+ ideal delay".)

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了
