q730是模拟低通转换为数字低通.q731是切比雪夫滤波器设计，q732椭圆带通数字滤波器的设计，其中用的是ellipord函数(q730 is converted to analog low-pass digital low-pass. q731 is a Chebyshev filter design, q732 elliptical band-pass digital filter design, which is used in a function ellipord)

A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems ... This is a simulink program for a continuous PID control system using Op-amps

考虑雨衰 阴影 和多径影响，利用自然梯度算法，非归零型差分相位调制信号建模与仿真分析 ，能量熵的计算，借鉴了主成分分析算法（PCA），基于负熵最大的独立分量分析，包括最小二乘法、SVM、神经网络、1_k近邻法。( Consider shadow rain attenuation and multipath effects Use of natural gradient algorithm, NRZ type differential phase modulation signal modeling and simulation analysis, Energy entropy calculation, It draws on principal component analysis algorithm (PCA), Based on negative entropy largest independent component analysis, Including the least squares method, the SVM, neural networks, 1 _k neighbor method.)

非常适合初学者的的matlab通信原理入门书，很多学校都用这个做教材！(Matlab Communication Theory Primer is ideal for beginners, many schools have done with this material!)

说明：  涡旋光束在光束的传播方向上有一个位相项e，而且它拥有一个光束轨道角动量，该matlab程序实现了从一个高斯基模变换到涡旋光束的基本功能。(The vortex beam has a phase term E in the direction of beam propagation, and it has a beam orbit angular momentum. The matlab program realizes the basic function of transforming from a Gaussian fundamental mode to a vortex beam.)
