Description: GMSK是高斯滤波的最小频移键控的简称，基本的工作原理是将基带信号先经过高斯滤波器成形，再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿，亦无拐点，因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then a minimum frequency shift keying (MSK) modulation. After forming as a result of the Gaussian pulse envelope without the steep edge, there is no inflection point, so the spectrum characteristics of the spectrum than MSK signal characteristics.

Description: making exponential signal with matlab
In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum).
For example an FSK signal can not simply downconverted to DC. because its spectrum is not symmetric around its center frequency, so you should downconvert it with exponential signal( the idea of using I and Q downconverter).
