说明：  gps信号的空域处理 包括gps阵列的模拟 空域的出算法(gps gps signal processing includes an array of airspace airspace of the algorithm simulation)

精通matlab综合辅导与指南，对于matlab的初学者很实用。(proficient Matlab comprehensive counseling and guidance for beginners Matlab practical.)

轴承故障模拟仿真程序，包括内圈、外圈及滚动体故障的matlab程序(Bearing Fault simulation procedures, including the inner and outer rings and rolling fault matlab program)

这个程序实现了一个mini的MAC系统，唯一的缺点是并没有考虑到功率限制的问题。(This program realise a system of minipac,the only shortcoming is that the lack consideration of power constraint.)

说明：  扩展卡尔曼滤波例程，data为数据，EKF是处理数据的函数(Extended Kalman filter routine, data for the data, EKF is a function of processing data)

m序列产生源程序，很好用！输入本源多项式，可生成指定长度，指定掩码，指定相位长度的序列(m Serial Generator.)

主要完成的工作是在监控的场景中检测出运动的物体，去除干扰的背景，只留下感兴趣的目标即目标提取。目标提取,运动信息提取,PCA和诊间差分方法。(The major work done to monitor the scene in the moving objects detected, remove the background interference, leaving only the object extraction target of interest. Object extraction, motion information extraction, PCA, and consultation between the difference method.)

功率谱估计的应用范围很广，在各学科和应用领域中受到了极大的重视。在《现代信号处理》课程中讲述了经典谱估计和现代谱估计这两大类谱估计方法；经典谱估计是基于傅立叶变换的，虽然具有运算效率高的优点，但是频谱分辨率低同时旁瓣泄漏严重，对长序列有着良好的估计。为了克服经典谱估计的缺点，人们开展了对现代谱估计方法的研究。现代谱估计是以随机过程的参数模型为基础的，有最大似然估计法、最大熵法、AR模型法、预测滤波器法。现代谱估计对短序列的估计精度高，同经典谱估计互为补充。在认真学习了现 代谱估计方法后，我选择了现代谱估计中的AR模型法的仿真作为题目。下面给出AR模型的相关理论和仿真实现。(Power Spectral Estimation of very extensive, in all disciplines and fields of application of a great deal of attention. The "modern signal processing" on the curriculum of classical and modern spectral estimation spectrum is estimated that the two types of spectrum estimation method; Classical spectrum estimation is based on Fourier transform, although high computing efficiency advantages, but also low-resolution spectrum Sidelobe serious leakage of long sequences have good estimates. In order to overcome the classic shortcomings of the spectrum estimation, there have been a pair of modern spectral estimation methods. Modern spectral estimation is the random process model parameters based on the maximum likelihood estimation, maximum entropy method, AR model, forecast filter. Spe)
