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

GSM中GMSK调制信号的产生，采用的是脉冲对消法，基于chebyshev的水声信号分析。- GSM is GMSK modulation signal generation, It uses a pulse of consumer law, Based chebyshev underwater acoustic signal analysis.
