说明：  用MatlaB编程实现GMSK在移动通信系统中的调制解调(Programming with MatlaB GMSK mobile communication system in the modulation and demodulation)

时频分布已被用来提供高分辨率表示大量的信号处理应用程序。然而,高分辨率和准确瞬时频率(如果)估计通常依赖于分布和使用信号相位函数的复杂性。(The time-frequency distribution has already been used to provide high resolution said a lot of signal processing applications. However, high resolution and accurate instantaneous frequency (if) estimates usually depends on the distribution and use of the complexity of the signal phase function.)

这个程序是计算信号的希尔伯特变换的，求信号瞬时相位，瞬时频率(This program is to calculate the signal of Hilbert transform, the signal instantaneous phase, instantaneous frequency)

说明：  数值计算啁啾光纤光栅(Numerical Calculation of chirped fiber grating)
