DC_AC

This folder has two files for the simulation od dc motor starting. please run the *.m file to run the *.mdl file(This folder has two files for the simulation od dc motor starting. please run the*.m file to run the*.mdl file)

almouti空时分组码matlab仿真实现，源码有点乱，望大家见谅(almouti space-time block codes matlab simulation implementation, source code a bit chaotic, hope you forgive me)

2D FDTD Codes with: standar formulation, flux density formulation, Mur ABC 1st and 2nd order, for TM mode

卡尔曼滤波器，用于平滑惯性器件的输出数据，从而可以对数据进行建模与补偿。 (Kalman filter, inertial device for smoothing the output data, allowing for data modeling and compensation.)

Another one usefull DTMF decoder model for Matlab Simulink with a lot of aux MathCAD computation.

用MATLAB绘制分形蕨的GUI程序，是非线性科学中分形理论的经典例子(MATLAB fractal fern GUI process, the nonlinear fractal theory of the classic examples)

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

再matlab上实现基于扩频的数字水印。图像处理(This is a simple spread-spectrum based informed watermarking implementation in MATLAB. )

时频信号分析技术，双线性方法，Wigner-Ville分布的应用，可以得到高斯包络线性调频信号的WVD图(Time-frequency signal analysis, bilinear method, Wigner-Ville distribution application, you can get WVD FIG Gaussian envelope chirp signal)

bpsk误码率，做毕业设计常用到的哦，题目是单入单出系统的误码率和信噪比的关系图(bpsk error rate, used to do Oh graduation, into a single topic is the system single-bit error rate and signal to noise ratio graph)
