DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt

ENERGY DETECTION THRESHOLD

cooperative sensing using AND technique

说明：  这里是一些代码，与matlab有关，是一些小技巧。(code, and the Matlab is some small skills.)

matlab应用程序百例，老师推荐的资源，很不错，可以下载看看(matlab application 100 cases, the teacher recommended resources, very good, you can download to see)

语音的端点检测 噪声可以自己加 使用阈值进行检测 能量的阈值跟据经验来进行决定(Speech endpoint detection noise can add to the threshold detection energy threshold according to experience to the decision)

K-means++算法实现，加强了初始聚类点的选取（careful seeding）(K-means++ algorithm to enhance the selection of the initial clustering points (careful seeding))

image processing central moments also called as Hu s moments and zigzag scan program

Geometrical transformation problems

该代码是lte数据传输中的加扰技术的源代码(The code is lte data scrambling technology in source code)
