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 methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

甚低频(VLF)谱图显示
Very Low Frequency (VLF) spectrograms show
sometimes sets of lines called MLR (Magnetospheric Line
Radiation) with frequency spacing close to 50 or 60 Hz. It is
very tempting to attribute these MLR to Power Line
Harmonic Radiation (PLHR). PLHR are the ELF and VLF
waves radiated by electric power systems at the harmonic
frequencies of 50 or 60 Hz. Here we show for the first
time large scale MLR observed simultaneously on
ground and on board a low altitude satellite which is
flying over the same zone.
