image quality measures

1、 生成多周期线性调频信号，并对其进行频谱分析； 2、 对仿真生成的信号利用两种窗口函数进行STFT变换生成时频分析图(1, to generate multi-cycle chirp signal, and its spectrum analysis 2, the signal generated by the simulation window function using two STFT transform to generate time-frequency analysis chart)

说明：  基于matlab，计算信号功率谱，调用了高阶谱分析工具箱的函数 bispecd 和 bispeci计算信号的双谱(Calculate signal power spectrum and bispectrum based on matlab)

MATLAB的基本操作与使用，对初学者很有帮助(MATLAB s basic operation and use, very helpful for beginners)
