OFDMSimulation
OFDM —— OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。此程序为ofdm仿真程序！(OFDM- OFDM (Orthogonal Frequency Division Multiplexing) that is orthogonal frequency division multiplexing, OFDM is the fact MCM Multi-CarrierModulation, a multi-carrier modulation. The main idea is: The channel is divided into a number of orthogonal sub-channel, high-speed data signals into parallel low-speed sub-data stream, modulated to be transmitted in each sub-channel. This program is ofdm simulation program!)

无限冲激响应低通滤波器的设计
%IIR数字滤波器的设计
%设计一个低通数字滤波器，设计指标：通带截止角频率为ωp，阻带截止频率为ωs，通带最大衰减为δp，阻带最小衰减为δs
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%冲激响应不变法%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
clc; clear all;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%利用巴特沃斯设计低通模拟滤波器%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
wp = 0.2*pi; ws = 0.3*pi; Deltap = -1; Deltas = -15;%低通数字滤波器设计指标
TS = 1;%采样时间TS
Wp = wp/TS; Ws = ws/TS; DeltaP = Deltap; DeltaS = Deltas; %求取模拟滤波器的设计指标
%确定巴特沃斯的阶数N和截止频率Ωc
N = log((10^(-DeltaP/10)-1)/(10^(-DeltaS/10)-1))/(2*log(Wp/Ws));
N = ceil(N); %模拟滤波器的阶数N
Wc = vpa( Ws/( ( 10^( -DeltaS/10 )-1 )^( 1/( 2*N ) ) ),5 )%模拟滤波器的截止频率Wc
%%获得模拟滤波器的系统函数H（s）

optics_toolkit
This toolkit has two main purposes.
1. Decomposition and visualization of paraxial beams in Hermite-Gaussian and Laguerre-Gaussian bases. (These functions are located in the subdirectory "transverse.")
2. Propagation of such beams through optical systems including two-mirror fabry-perot cavities. (These functions are located in the subdirectory "axial."
