:数字水印技术在数字产品的版权保护中起着非常重要的作用。概括了数字水印技术的现状及其基本原理,并 分析了变换域数字水印算法的优势,详细阐述了DCT 水印嵌入和提取算法的原理和步骤。最后在Matlab 平台下对DCT 数 字水印算法进行了仿真,仿真结果证实了DCT 算法的强健性和鲁棒性。(: digital watermarking technology in the digital copyright protection products played a very important role. Summarized the digital watermarking technology and the status of the basic principles and transform domain analysis of digital watermarking algorithm advantages, elaborate on the DCT watermark embedding and extraction algorithm theory and steps. Finally in Matlab platform for DCT digital watermarking algorithm for the simulation, Simulation results confirmed the DCT are strong and robust.)

matlab code to calculate the LMS algorithm vector

本程序是对V-BLAST系统及其检测算法的仿真，可采用BPSK,QPSK,16QAM,64QAM调制。检测算法为ML，MMSE,ZF,以及采用迫零的连续干扰消除检测算法。(This procedure is the V-BLAST system and its detection algorithm simulation, can be used BPSK, QPSK, 16QAM, 64QAM modulation. Detection Algorithm for the ML, MMSE, ZF, and the use of zero-forcing successive interference cancellation algorithm.)

LDA MATLAB的算法，可以加入iris数据，并且直接可以使用的(LDA MATLAB algorithm, can join the iris data, and can be used directly)

辨识所使用的数据长度保持不变，每增加一个新数据就抛掉一个老数据，使参数估计值始终只依赖于有限个新数据所提供的新消息，克服了遗忘因子法不管多老的数据都在起作用的缺点，因此该算法更能有效的克服数据饱和现象。(Identify the use of data length remain the same, every time you add a new data will throw away an old data, make the parameter estimate always depends on just co., LTD., a new data provided by the new news, overcome the forgetting factor method no matter how old data are in action shortcomings, so the algorithm can effectively overcome the more data saturation phenomenon.)
