直接序列扩频通信系统误码率的仿真分析PN码同步方法的比较与仿真(this is a pn sequences mode)

Basic Kalman filter, heavily commented, for beginners to Kalman filtering.

该源码是用MATLAB语言编写，目的是实现序列特征选却和RBF网络功能(The source code is written in MATLAB language, purpose is realized and the RBF network function is selected sequence characteristics)

基于DCT的图像处理，MATLAB例程。。。。。。、(DCT-based image processing, MATLAB routines. . . . . . ,)

利用自然梯度算法，ML法能够很好的估计信号的信噪比,考虑雨衰 阴影 和多径影响。( Use of natural gradient algorithm, ML estimation method can be a good signal to noise ratio, Consider shadow rain attenuation and multipath effect.)

求解出在最小均方误差滤波器单位冲激函数h(n)。求解过程需要通过利用循环嵌套的编程思想，比较在逐次增加滤波器阶数的过程中得到的最小均方误差与最初设定的最小均方误差的阈值，当达到要求时，可以进一步确定滤波器的阶数。(how to use this function: [hx,hy]=wiener_ch2(w,N) )

Some of the files model satellite formation for a leader and follower configuration while others relate direction cosine transformation for 3-1-3 rotation

这篇文章是通过改进的RD算法对大斜视角SAR进行仿真，通过仿真验证这种改进的算法是可行的。对研究雷达的人有帮助！(This article is simulation for large squint SAR by improving the RD algorithm.The result is demonstrated the improved algorithm is feasible。 It is useful for the poople that study the radar。)

利用求根MUSIC算法进行ＤＯＡ估计的源程序(Root MUSIC algorithm using the DOA estimation of the source)

matlab采用半色调技术对图像进行显示：用模板近似表示10个灰度级，每一个灰度级用3*3 的模板来表示，并对如下图所示的256*256的渐变图像进行半色调输出的检验。(matlab using halftoning image display: template approximated 10 gray levels, a gray level of each template used to represent the 3* 3, and the gradation of the image as shown in Figure 256* 256 halftone inspection of the output.)
