Abstract

As a promising technique in mitigating extremely strong and broadband jamming, active anti-jamming (AAJ) allows a transmitter node to send messages by re-modulating jamming signals with programmed amplification factors. However, how to optimize these amplification factors is still an open issue. In this letter, we propose an energy-efficient design for AAJ-enabled communications systems. In particular, the energy efficiency problem is studied and formulated as the total energy consumption minimization subject to the minimum required rate and the hardware limit of the power amplifier, which turns out to be a quadratic programming problem. The corresponding optimal amplification factors are obtained by the interior point method. Numerical results indicate that with the equal transmission rate, the proposed energy-efficient AAJ scheme can provide 76.8% energy saving as compared with the direct transmission.

主动反干扰（AAJ）通信系统的节能设计

主动抗干扰技术（AAJ）是一种很有前途的缓解极强和宽带干扰的技术，它允许发射节点通过对干扰信号进行重新调制，并设定放大系数来发送信息。然而，如何优化这些放大系数仍是一个未决问题。在这封信中，我们为支持 AAJ 的通信系统提出了一种节能设计。具体来说，我们研究了能效问题，并将其表述为在最小所需速率和功率放大器硬件限制条件下的总能耗最小化，这变成了一个二次编程问题。通过内点法得到了相应的最佳放大系数。数值结果表明，在传输速率相同的情况下，所提出的高能效 AAJ 方案比直接传输节能 76.8%。
