论文摘要
为了为配备有频率多样性阵列（FDA）的实用通信系统提供系统设计见解，本文研究了利用有限的alphabet输入的FDA系统的保密性能，而不是波动的两射线（FTR）褪色通道。更具体地说，得出了平均保密率（ASR）和保密中断概率（SOP）的闭合形式表达式，而其正确性则通过数值模拟确认。此外，我们执行渐近分析，以量化高斯和有限词组输入之间的保密性能差距，以实现主要通道的足够大的平均信噪比（SNR）。与基于高斯输入的研究相比，这封信着重于实用场景，这些方案阐明了FDA系统属性。
To provide system design insights for practical communication systems equipped with the frequency diverse array (FDA), this paper investigates the secrecy performance of FDA systems exploiting finite-alphabet inputs over fluctuating two-ray (FTR) fading channels. More specifically, closed-form expressions for the average secrecy rate (ASR) and the secrecy outage probability (SOP) are derived, while their correctness is confirmed by numerical simulations. In addition, we perform asymptotic analysis to quantify the secrecy performance gap between Gaussian and finite-alphabet inputs, for a sufficiently large average signal-to-noise ratio (SNR) of the main channel. Compared with Gaussian inputs-based research, this letter focuses on practical scenarios which sheds lights on properties of FDA systems.
