使用Hilbert变换的隐形标志水印，通过置乱变换对水印，使得水印的鲁棒性和透明性增强(Stealth watermark, which uses Hilbert transform, improves the robustness and transparency of the watermark by scrambling the watermark to the watermark.)

国外嵌入式面试常见试题，快要毕业的朋友们，学习嵌入式的同志们，进来看看。-Embedded foreign common interview questions, about to graduate from friends, learning embedded Comrades, come take a look at.

光伏单元输出特性 本模型使用的是simulink搭建，极好的显示了光伏单元电压电流和电压功率的输出特性，为mppt最大功率追踪奠定基础。(Output characteristics of photovoltaic cells)

AUTOLISP CAD批量将圆变成以圆心为坐标的点(Circular change point)

说明：  混沌扩频通信，其中包括混沌信号产生，加高斯噪声，以及调制解调。(Chaotic spread spectrum communication includes chaotic signal generation, Gauss noise, and modulation and demodulation.)

说明：  多元经验模式分解（MEMD）算法是EMD算法从单个变量到任意数量的变量的扩展，其与经验模态分解一样存在模式混合问题，基于噪声辅助的多元经验模式分解（NAMEMD）就在对MEMD的改进，解决其问题。(The multiple empirical mode decomposition (MEMD) algorithm is an extension of the EMD algorithm from a single variable to any number of variables. Like the empirical mode decomposition, there is a mode mixing problem. The noise-assisted multiple empirical mode decomposition (NAMEMD) is just Improve and solve its problems.)

轮廓波变换的基本原理，对输入图像的进行轮廓波变换，并重构原始信号(The basic principle of contourlet transform, performing contourlet transform on the input image and reconstructing the original signal.)

说明：  数字无线电课程设计代码，代码含有详细的注释(Digital radio course design code with detailed notes)
