使用深度神经网络进行干扰分类

Interference Classification Using Deep Neural Networks

Jianyuan Yu, Mohammad Alhassoun, R. Michael Buehrer

摘要:

最近在实现监督学习来分类调制类型方面的成功表明,类似于调制分类的其他问题最终将受益于该实现。这些问题之一是对添加到感兴趣信号的干扰类型进行分类,也称为干扰分类。在本文中,我们提出了一种使用深度神经网络的干扰分类方法。我们生成五种不同类型的干扰信号,然后使用接收信号的功率谱密度(PSD)和循环谱作为网络的输入特征。计算机实验表明,利用接收信号的功率谱密度比利用其循环谱的精度更高。此外,相同的实验表明,前馈网络产生更好的精度比经典的方法。所提出的分类器辅助接收器链中的后续阶段选择适当的缓解算法,并且还可以与调制分类方法共存,以进一步提高分类器的准确性。

英文摘要:

The recent success in implementing supervised learning to classify modulation types suggests that other problems akin to modulation classification would eventually benefit from that implementation. One of these problems is classifying the interference type added to a signal-of-interest, also known as interference classification. In this paper, we propose an interference classification method using a deep neural network. We generate five distinct types of interfering signals then use both the power-spectral density (PSD) and the cyclic spectrum of the received signal as input features to the network. The computer experiments reveal that using the received signal PSD outperforms using its cyclic spectrum in terms of accuracy. In addition, the same experiments show that the feed-forward networks yield better accuracy than classic methods. The proposed classifier aids the subsequent stage in the receiver chain with choosing the appropriate mitigation algorithm and also can coexist with modulation-classification methods to further improve the classifier accuracy.
