干扰环境下通信信号的调制识别技术研究

Research on modulation recognition technology of communication signals in interference environment

  • 摘要: 自动调制样式识别是非合作通信场景中实现信号检测和解调的关键前提。近年来,深度学习在自动调制样式识别领域展现了显著的优势。然而,现有研究普遍忽视了通信过程中随机干扰所带来的挑战。事实上,由于无线通信的开放性和广播特性,干扰攻击已成为无线通信中的重大威胁。为了充分发挥自动调制样式识别在无线通信中的潜力,本文深入探讨了干扰环境下基于深度学习的调制样式识别技术。具体而言,本文针对已知干扰和随机未知干扰两种情况,设计了相应的基于干扰认知的识别方法,并通过开放数据集RML2016.10a验证了所提算法的有效性。

     

    Abstract: Automatic modulation recognition is a critical prerequisite for achieving signal detection and demodulation in non-cooperative communication scenarios. In recent years, deep learning has demonstrated significant advantages in this field. However, existing studies have largely overlooked the challenges posed by random interference and jamming during communication. In fact, due to the open and broadcast nature of wireless communications, interference and jamming attacks have become major threats. To fully harness the potential of automatic modulation recognition in wireless communications, we have conducted an in-depth exploration of deep learning-based modulation recognition techniques under interference and jamming conditions. Specifically, we propose corresponding recognition methods based on interference recognition for scenarios where interference is either known or unknown, and we have validated the effectiveness of our proposed algorithms using the open dataset RML2016.10a.
