说明：  STOMP压缩感知算法，可以重构一维信号，来源于jbb0523(Stomp compressed sensing algorithm, which can reconstruct one-dimensional signal, comes from jbb0523)

ofdm系统的matlab实现，包括插入导频信号和循环前缀(Matlab implementation of ofdm system, including inserted pilot frequency signal and the cyclic prefix)

说明：  在MatLab中，利用角谱理论，模拟了物体经过透镜成像的过程。 例子中 物体为读入的图像(五角星)，在放大倍数为1、2、6倍的情况下分别模拟。(Using the angle spectrum theory to simulate the imaging process of an object passing through a lens in MATLAB, In the given example, the object is a read-in image (a pentagram), which is simulated with magnification of 1, 2 and 6.)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

小波变换，小波矩特征提取方法，特别好用，注释清楚(Wavelet transform, wavelet moment feature extraction method, particularly easy to use, annotated clearly.)

用于无人自动舰艇的直行，转弯控制，内含simulink仿真(No auto-ship for the straight, turn control, containing simulink simulation)

This circuit takes 10V trigger pulse to trigger a triac which connect the points A and B together. This circuit can be placed to almost any stroboscope ...

is the handbook of wirelesss network. very usefull if you work on the physical layer.
