描述了用MATLAB实现升余弦滚降滤波器的方法(USING MATLAB)

说明：  平方根升余弦脉冲实例。两个SQRC滤波器的级联组合就成为一个零ISI的滤波器。此程序用于获得平方根升余弦脉冲。(Square root raised cosine pulse instance. Cascade combination of the two SQRC filters to filter a zero ISI. This procedure used to obtain the square root raised cosine pulse.)

应用KNN算法解决0到9的手写数字识别问题，效果在90 以上，内部有两个数据集，一个为训练集（7291个数据），一个为测试数据（2791个数据），程序采用MATLAB编写，另附有文档，程序简洁易懂(Application KNN algorithm to solve 0-9 handwritten digit recognition problem, the effect is more than 90 , the inside has two data sets, one for the training set (7291 data), a test data (2791 data), the program written using MATLAB , attached a document, the program is simple and easy to understand)

这个代码可以画出一个具有一定倾角的规则长城(This code can draw a certain angle with the rules of the Great Wall)

Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise is Gaussian distributed with mean=0 and  2 = 1.

说明：  JC验算点法matlab程序设计。里面使用了当量正态法进行计算(JC checking point method matlab program design. Which use the equivalent normal method calculated)

利用matlab实现标记算法，本人已运行，好用(Marking algorithm using matlab, I have to run, easy to use)

大量实验表明,提出的方法对同种传感器或者不同传感器图像之间的配准都是有效的。 提出了一种新的基于角点检测的图像配准方法,其核心思想是采用一种快速的 基于图像灰度的角点检测新算法,通过沿圆弧曲线扫描获取角点信息,然后根据这些 角点信息建立图像间角点的对应关系,并由此得到初配准参数,最后通过迭代过程以 提高配准的精度. 理论分析和实验结果表明,该算法对图像间的旋转角度没有限制, 配准精度高而且计算量较小. (Experiments show that the proposed method on the same kind of sensor or between the different sensor image registration is valid. A new corner detection based image registration method, the core idea is to use a fast gray-based new algorithm for corner detection, scanning through the curve along the arc for corner information, and then based on these corner information to establish image correspondence between the corners, and thus be the beginning of registration parameters, and finally through the iterative process to improve the accuracy of registration. Theoretical analysis and experimental results show that the algorithm is rotation between the image does not limit , registration accuracy and less computation.)
