- 现有数字信号自动调制识别方法大多只适用于无记忆信号,如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑,提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数,采用多层神经网络作为分类器。计算机仿真表明:当噪声采用高斯白噪声,并且信噪比大于 l5 dB时,识别率高于96% ;当信噪比不低于l0 dB时,识别率不低于90%。,Existing digital signal automatic modulation recognition

GMSK
- 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
