AI 中文摘要

我们提出了用于端到端自动调制和隐蔽信道(CC)识别的E-SpecFormer(边缘频谱监测变压器)。我们引入了LiTAN(线性双曲正切注意力网络),一种无Softmax和层归一化的注意力机制,可在提高射频任务准确性的同时降低复杂性。E-SpecFormer有四种可扩展变体(Nano、Small、Medium、Large)进行参数化,以适应不同的硬件约束。使用RadioML2018数据集进行调制识别,Nano变体在信噪比>0 dB时平均准确率达到86.5%,在基于硬件木马(HT)的CC数据集上准确率达到94.2%,参数少于10k,在FPGA/CPU协同执行时每帧速度高达92微秒,以低成本超越了现有边缘模型。这些结果表明E-SpecFormer是物联网(IoT)设备实时频谱智能的边缘高效解决方案。

英文摘要

We present E-SpecFormer (Edge Spectrum monitoring Transformer) for end-to-end automatic modulation and covert channel (CC) recognition. We introduce LiTAN (Linear Tanh Attention Network), a Softmax- and LayerNorm-free attention mechanism that reduces complexity while increasing accuracy in RF tasks. E-SpecFormer is parameterized in four scalable variants (Nano, Small, Medium, Large) to accommodate diverse hardware constraints. Using the RadioML2018 dataset for modulation recognition, the Nano variant achieves 86.5% average accuracy for Signal-to-Noise Ratios (SNRs)>0 dB, and on the hardware Trojan (HT)-based CC dataset it reaches 94.2% accuracy, both with fewer than 10k parameters and up to speed of 92 μs per frame on FPGA/CPU co-execution, surpassing state-of-the-art edge models at a fraction of their cost. These results establish E-SpecFormer as an edge-efficient solution for real-time spectrum intelligence on Internet of Things (IoT) devices.
