Abstract:
A decision tree structure is proposed to handle automatic modulation classification under mixed noise and fading channels. In the first layer of the tree, IQ signals are categorized into three groups according to the error entropy. In the second layer, IQ signals preprocessed by Cauchy-Score functions are fed as patterns into the neural network where global and local features are abstracted by Transformer and CNN parallelly and concatenated to make a final decision. Monte-Carlo experiments demonstrate the superiority of the proposed method, strategy and network under mixed noise and fading channels.
