论文摘要
在对抗性电子攻击（例如宽带干扰攻击）下提供质量通信是一项艰巨的任务。与将干扰信号视为破坏性干扰的最先进的方法不同，本文为堵塞的频道提出了一种新型的主动抗障碍（AAJ）方案，以增强发射机节点（TN）和接收器节点（RN）之间的通信质量（TN）在TN中积极利用jamming信号作为载体作为载体作为发送消息的渠道。具体而言，TN配备了可编程增益放大器，该放大器能够重新调节用于干扰调制的干扰信号。考虑到四种典型的干扰类型，我们既得出了AAJ方案的位错误率（BER）和相应的最佳检测阈值。在高障碍比（JNR）和采样率案例下，讨论了AAJ方案的渐近性能。我们的分析表明，存在一个足够大的JNR的BER地板。仿真结果表明，提出的AAJ方案允许TN与RN交流，即使在极强和/或宽带干扰下也可以可靠地通信。此外，我们研究了提出的AAJ方案的通道容量，并表明AAJ方案的通道容量在JNR相对较高时优于直接传输的通道容量。
Providing quality communications under adversarial electronic attacks, e.g., broadband jamming attacks, is a challenging task. Unlike state-of-the-art approaches which treat jamming signals as destructive interference, this paper presents a novel active anti-jamming (AAJ) scheme for a jammed channel to enhance the communication quality between a transmitter node (TN) and receiver node (RN), where the TN actively exploits the jamming signal as a carrier to send messages. Specifically, the TN is equipped with a programmable-gain amplifier, which is capable of re-modulating the jamming signals for jamming modulation. Considering four typical jamming types, we derive both the bit error rates (BER) and the corresponding optimal detection thresholds of the AAJ scheme. The asymptotic performances of the AAJ scheme are discussed under the high jamming-to-noise ratio (JNR) and sampling rate cases. Our analysis shows that there exists a BER floor for sufficiently large JNR. Simulation results indicate that the proposed AAJ scheme allows the TN to communicate with the RN reliably even under extremely strong and/or broadband jamming. Additionally, we investigate the channel capacity of the proposed AAJ scheme and show that the channel capacity of the AAJ scheme outperforms that of the direct transmission when the JNR is relatively high.
