simulink框图来实现多进制PAM调制(simulink block diagram to realize the M-ary PAM modulation)

MATLAB学习的很好的PPT资料，基础matlab学习者的首选教材演示(matlab study)

分别对正弦波，三角波，方波，一周期内取为整数的64个点（A=4095）；写锯齿波和方波的谐波构成（只写了3、4个）。(Of sine wave, triangle wave, square wave, A week off for integer in the period of 64 points (A = 4095) Write a sawtooth wave and square wave of harmonic (only wrote 3, 4).)

DCT域QIM音频隐藏技术的实现——信息隐藏技术 (QIM realize DCT domain audio hiding techniques- Information Hiding)

DMC MPC 动态矩阵预测控制 非常好 图像清晰 并且有控制前后曲线对比。控制效果好 MATLAB编程 自动化(MPC DMC dynamic matrix predictive control is very good image is clear and there is control before and after the curve contrast. Control effect is good MATLAB programming automation)

采用FIR最小二乘逆滤波器来实现反卷积 1.通过输入信号xn与传递函数gn求输出yn 2.通过使平方误差达到最小求出最佳延迟 3通过最佳延迟求得逆滤波器传递函数hn 4通过hn与yn进行卷积运算得到还原的输入信号xn1，进行对比 5按照题设要求，进行相关噪声添加，再次进行上述实验过程 (Using least squares FIR inverse filter to achieve deconvolution)

这是偶自己的作品拉，基于matlab环境，作的图象压缩实验，分别ＤＷＴ与ＳＷＴ作对比参照实验(This is the duality gap own work, based on the matlab environment, for the image compression experiments, DWT and SWT, respectively, compared with reference to experimental)

实现chirp信号，可调的指标，是一个很好的程序(Achieve chirp signals, adjustable target, is a good program)

好用的matlab实现凸优化工具包，适用于压缩感知重构过程(Easy to use matlab to achieve a convex optimization tool kit for compressed sensing reconstruction process)

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (Themohu function is used in mainly control applications. PIDCalc performs one iteration of the PID algorithm. While the PID function works, main is just a dummy program showing a typical usage.)
