数字水印源码，基于matlab的，可实现，共同分享。(Digital watermarking source code, based on the matlab can be realized.)

brisk描述子,matlab语言，好懂易学(brisk descriptors, matlab language, easy to understand to learn)

首先确认安卓手机硬件的蓝牙模块是否支持蓝牙4.0. （手机硬件模块不支持的话，软件做的在正确也连不上！） 2. 系统升级到4.3 或更新版本 3. 资料包内的 HMBLEComAssistant.rar 可用于测试 收发(AT+BAUD0 AT+NAMEAC AT+PASS000000 //必须输入满6位 AT+TYPE1 AT+ROLE0)

衡量一个数字通信系统性能好坏的指标很多，误码率性能就是一个重要的指标。误码率是指错误接收的码元数载传输总码元数中所占的比例。在该章中，我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下(A digital communication system performance measure indicators of good or bad a lot of bit error rate performance is an important indicator. Bit error rate refers to the number of errors contained in received transmission symbol the number of total yards per share. In this chapter, we will send through MATLAB simulation of average power and transmission rate in the same circumstances)

说明：  rsa示例，实现了加密和解密的基本功能，供大家参考(rsa example, to achieve the basic functions of encryption and decryption, for your reference)

关于CORBA 通信的描述和开发，原理和 概念 ，中文版 (The description on the CORBA communication and development, principles and concepts, the Chinese version)

说明：  这是二战时期著名的，独领一时风骚的密码机Enigma的源代码，它真实的再现了Enigma的工作原理和真实原貌，希望有兴趣的朋友共同参详(This is the famous World War II, was the sole lead of 1:00 coquettish Enigma cipher machine source code, it is a true reproduction of the working principle of the Enigma and true original, want to have a friend interested in the common parameters are set)

Windows下的ICMP封装(Clcmp class which can echo)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)

在分析结构损伤后，给结构添加噪声，再对结构不同损伤情况下的分析(After the analysis of structural damage to the structure adding noise, and then the structure is different in case of damage)
