this package contain a function generate a barker code sequence which is used in phase coded pulse compression performed in the second matlab file

说明：  这个水印一般般利用DWT变换和DCT变换嵌入水印，加上了Arnold变换使图片水印的抗MP3压缩攻击有所提高。(The watermark in general as the use of DWT transform and DCT transform embedded watermark, coupled with the Arnold transform to image watermarking against MP3 compression attacks increased.)

英语相关的学习方法，很好的学习资料，还有一些时间的内容。(English-related learning, good learning materials, and some time content.)

在 Matlab/Simulink 中，建立独立的功能模块，如电机本体模块、矢量控制模块、速度控制模块、电流滞环控制模块等，再进行功能模块的有机整合，搭建交流异步电机控制系统的仿真模型。(In M atlab/Simulink, the independent function al blocks, such as Moter modelblock,Vector control block, Speed controller block, and Hysteresis current controllerblock etc,have been modeled. By the organic combination of these blocks, the model of control system canbe establishedeasily. )

通过给定天线阵列的参数，计算出切比雪夫馈电电流分布，并计算出方向图(By giving the parameters of the antenna array, the current distribution of the Chebyshev feed current is calculated and the direction map is calculated.)

说明：  学习阶段自己写的，语音信号去噪的matlab程序，希望大家给出批评指正意见。(Stages of learning to write their own, the speech signal denoising matlab program, hope that we are given the views of critics correction.)

分析了ofdm系统的过程，包括发送接收和送入信道加入噪声和多址的过程(ofdm system of the process, including the transmission and reception into the channel by adding noise and multi-site process)

利用MATLAB编制的绘图程序，对利用自己开发绘图界面很有启发(using MATLAB based mapping procedures, the development of the use of their graphics interface is very enlightening)

核磁共振方法是一项尖端技术，在物理学和医学等领域有着较普遍的应用。 其无损性和高分辨率的特点是这项技术最大的优势。而利用核磁共振方法来找水 是其在地学中应用的一个新领域，为地球物理方法提供了新的思路。(NMR is a cutting-edge technology, medicine and other fields in physics and has more general application. The high-resolution non-destructive and are characterized by the biggest advantage of this technology. The use of NMR to come to learn that water is applied in a new area for geophysical methods to provide a new way of thinking.)

用于信号处理中的峰值检测，里面有demo，可以直接运行(peak finder)
