CLASSIFICATION OF RADAR SIGNALS

CDMA Simulation Using MATLAB This program models a simple implementation of CDMA technology. It considers multiple bit data streams sent by any number of senders across a common channel. Each sender uses a unique code word, given by the Walsh set, to encode its data, send it across the channel, and then perfectly reconstruct the data at the receiver. The simulation utilizes these simplifications: 1. The individual data streams share the same bit length. 2. The code words are determined using the Walsh set to create orthogonal code words. 3. The spreading factor M of each code word is identical. 4. All users (data streams and codes) are synchronized in time. 5. Set-up and hold times of real-world systems are ignored. 6. The channel through which the data passes is ideal.

基于局部图划分的多相活动轮廓图像分割模型，很好的一篇文章(Partitioning and based on local image multi-phase active contour segmentation model, very good article)

在简要介绍MATLAB语言的基础上，对使用MATLAB语言仿真的CDMA通信系统进行描述。(in MATLAB briefed on the basis of on the use of MATLAB simulation of CDMA communications system description.)

该程序可以用于语音信号的倒谱运算，其他一维信号也适用(The program can be used for speech signal cepstrum computing also applies to other one-dimensional signal)

说明：  使用matlab实现希尔伯特黄变换中的经验模态分解，可以抑制信息处理中的端点问题(pelease keep it ,it is useful!)
