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)

很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )

流行学习的matlab代码，图形界面，操作简单，有说明。(Popular learning matlab code, graphical interface, simple operation, it has made it clear.)

先定义蔡氏方程，再利用ode45画出蔡氏方程的分岔图(we give the equation of chua,then use ode45 function to solve and plot the bifurcation diagram.)

通过AR模型模拟得到风荷载，其模拟是有davenport风速谱得到的(By AR model simulation of wind loads, and its analog davenport wind speed spectrum)
