Phase-shift keying (PSK) is a method of digital communication in which the phase of a transmitted signal is varied to convey information. There are several methods that can be used to accomplish PSK.

这个matlab程序用于实现广义高斯分布的参数估计，非常有用(Matlab program for the realization of the generalized Gaussian distribution of parameter estimation, a very useful)

To calculation the BER of Qpsk overAWGN ang Rayleigh Fading channel

自己编写的用matlab实现概念格的程序，用来求得所有的概念(I have written the concept lattice using matlab procedures used to obtain all of the concepts)

一个师兄的毕设，自己编的5种调制信号，微分方程组数值解方法。( A complete set of brothers, Own five modulation signal, Numerical solution of differential equations method.)

matlab小波变换源代码，供广大研究者学习(matlab wavelet transform source code, for the majority of researchers to learn)

小波模极大值去噪，Denoise_w_Mod_sim.m是主程序，P_gama.m，P_y.m，Py_Pgama.m是三种投影算法(Wavelet modulus maxima denoising, Denoise_w_Mod_sim.m is the main program, P_gama.m, P_y.m, Py_Pgama.m are three projection algorithm)

图像特征提取以及匹配，sift代码。可用于图片检索中，同比SURF，其算法可以较好的识别图像中文字(Image feature extraction and matching, sift the code. Can be used for image retrieval, up by SURF, the algorithm can better identify the image text)

扩展Klman滤波在车辆GPS/DR组合定位系统信息融合中的应用，主要包括：产生车辆运行轨迹，GPS卫星单独定位导航，DR车辆航迹单独定位导航，GPS/DR通过扩展卡尔曼滤波进行多源数据融合实现的组合定位导航。产生的结果有车辆实际运动轨迹，车辆在GPS定位下的运动轨迹，车辆在DR定位下的运动轨迹，车辆在GPS/DR数据融合后组合定位轨迹，以及各种定位方式在北向和东向各自的误差图。(The extended Klman filter in vehicle GPS/DR integrated navigation system information fusion application, mainly including: the generation of vehicle trajectory, GPS satellite positioning and navigation of vehicle track alone, DR alone, GPS/DR positioning and navigation, by extending the Calman filter to achieve multi-source data fusion combined navigation. The result of actual vehicle trajectories, trajectories of vehicles in GPS positioning, DR positioning in the vehicle trajectory, vehicle location trajectory in GPS/DR after data fusion, as well as a variety of ways to locate and east the error map in the north.)

说明：  通过纵向速度控制与侧向路径跟随，实现车辆轨迹跟踪功能(Through longitudinal speed control and lateral path following, the function of vehicle trajectory tracking is realized)
