好用的线性调频脉冲压缩测试源程序

车辆信号的震动信号的滤波、幅值以及能量分析，信号是利用测试台采集回来的。(Vehicle vibration signal filtering signals, amplitude and energy analysis, the signal is the use of test collection back.)

通过边界延拓方法，改进的利用维纳滤波实现模糊图像的复原。(Through the boundary extension method, the improved Wiener filter using the fuzzy image restoration.)

此程序为机动目标的非线性滤波器的设计，具有一定的实用价值(This program design of nonlinear filters for maneuvering targets, has some practical value)

CSMA/CD(1-persistent): 当有packet需要发送时： • 如检测到信道空闲，发送packet • 如检测到信道忙，一直检测信道状态，一旦信道空闲，立即发送(CSMA/CD (1-persistent): When there is packet needs to be sent when: • If the channel is detected idle, transmit packet • If the channel is detected busy channel state has been detected, once the channel is idle, transmit immediately)

资源描述利用小波变换把含噪信号分解到多尺度中，小波变换多采用二进型，然后在每一尺度下把属于噪声的小波系数去除，保留并增强属于信号的小波系数，最后重构出小波消噪后的信号。其中关键是用什么准则来去除属于噪声的小波系数，增强属于信号的部分。其中,若对小波系数进行阈值处理，就可以在小波变换域中去除低幅度的噪声和我们所不期望的信号;然后进行离散小波变换逆变换，尽管所恢复信号丢失了一点细节(对应小尺度时的幅度较小的小波变换系数)，但仍将恢复我们所期望的信号。

说明：  基于matlab的图像识别源代码，值得学习，不过是英文的(Image Recognition source on matlab)

一种简单的代数重建算法，用于CT图像二维重建，供初学者学习使用。(A simple algebraic reconstruction algorithm, used in CT image reconstruction, for beginners learning to use.)

说明：  k-means算法是一种简单的迭代型聚类算法，采用距离作为相似性指标，从而发现给定数据集中的K个类，且每个类的中心是根据类中所有值的均值得到，每个类用聚类中心来描述。对于给定的一个包含n个d维数据点的数据集X以及要分得的类别K,选取欧式距离作为相似度指标，聚类目标是使得各类的聚类平方和最小(K-means algorithm is a simple iterative clustering algorithm, which uses distance as a similarity index to find K classes in a given data set, and the center of each class is based on the mean of all the values in the class, and each class is described by the cluster center. For a given data set X containing N d-dimensional data points and the category K to be scored, the Euclidean distance is selected as the similarity index, and the clustering objective is to minimize the sum of squares of all kinds of clustering.)
