Quatre_QAM_AWGN

这个是用MATLAB写得 关于切比雪夫多项式展开的程序，输入一个函数 可以直接得到切比雪夫的展开时 很方便(This is written in MATLAB about the Chebyshev polynomial expansion program, enter a function can be very convenient Chebyshev expansion)

gsc 广义旁瓣消除器的MATLAB源程序(gsc GSC MATLAB source device)

[sigma,mu,A]=mygaussfit(x,y) [sigma,mu,A]=mygaussfit(x,y,h) this function is doing fit to the function y=A * exp( -(x-mu)^2 / (2*sigma^2) )

说明：  CT重建算法，迭代算法ARTII，乘型ART算法，该算法法比初始值选择不能为0(CT reconstruction algorithm, iterative algorithm ARTII, x-ART algorithm, The algorithm method than the initial value of options can not be 0)

Poincare Index法提取指纹中心点(Poincare Index extraction fingerprint center)

用matlab编程对电压信号用离散化傅里叶级数变成求各次谐波含量(Matlab programming voltage signal with a discrete Fourier series becomes the harmonic content of each request)

任意波形源的pwm信号生成电路控制桥式结构 其中上面是双极式调制pwm考虑了上下桥臂不能同时开通（加了延迟）；下面是受限单极式调制pwm信号发生器(Pwm arbitrary waveform signal generating circuit bridge structure wherein the control source is a bipolar modulator pwm at the upper and lower arms can be considered simultaneously opened (with delay) following is limited single modulator pwm signal generator)

这个是谱减法的MATLAB程序，经过验证能比较好的去除平稳噪声。其运用了简便的FFT减小了运算量(it is a program about delete noise.it based on MATLAB)
