代码说明:

  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.)
