利用MATLAB编写的关于频谱细化(Zfft)的程序,有注释。(Spectrum zoom (Zfft) program using MATLAB There are notes in it. )

本matlab程序用共轭梯度法来求解多元模型的最小值（给出最小值和精度情况）(The matlab program conjugate gradient method to solve the minimum multivariate model (given the minimum and the accuracy of the situation))

1、用Matlab绘制带通信号图形 2、用Matlab对模拟信源进行均匀量化 3、用Matlab编制一个函数实现均匀PCM量化编码，并计算量化噪声比(SQNR) 4、用Matlab对不同的量化级数计算出相应的量化噪声比(1, drawn using Matlab graphics bandpass 2, the simulation using Matlab source for uniform quantization 3, prepared using Matlab function to achieve a uniform PCM quantization coding, and calculate the quantization noise ratio (SQNR) 4, using Matlab on a different series to calculate the corresponding quantitative quantization noise ratio)

一些直扩和跳频的程序，还有CDMA的程序(DSS、FH、CDMA)
