matlab 数字水印的处理，可实现文件的加密处理(matlab digital watermark processing, encrypted files can be realized)

两个正弦信号叠加白噪声 用fft进行频谱分析(failed to translate)

OFDM仿真原始代码。基于matlab实现OFDM的全过程。压缩文件中包含7个文件。(OFDM code files, include the whole procedure of OFDM. there are seven files in this package.)

《MATLAB程序设计教程》刘卫国第一版 源代码 水利水电出版社(" MATLAB Programming Guide" Liu Weiguo first edition of the source code Waterpower Press)

包括面积、周长、矩形度、伸长度，DC-DC部分采用定功率单环控制，基于分段非线性权重值的Pso算法，包含光伏电池模块、MPPT模块、BOOST模块、逆变模块，最小二乘回归分析算法，PLS部分最小二乘工具箱,仿真效果非常好。( Including the area, perimeter, rectangular, elongation, DC-DC power single-part set-loop control, Based on piecewise nonlinear weight value Pso algorithm, PV modules contain, MPPT module, BOOST module, inverter module, Least-squares regression analysis algorithm, PLS PLS toolbox, Simulation of the effect is very good.)

说明：  it just a simple code in matlab for image zooming
