论文摘要
在本文中，我们考虑了一种新的安全空间调制场景，具有全双工（FD）恶意攻击者Mallory拥有窃听能力的能力，其中Mallory在FD模型上工作，并传播了一种恶意堵塞，例如人造噪音（AN），以与Bob交流。为了抑制Mallory的鲍勃（Bob）上的恶意障碍，首先提出了鲍勃（Bob）的常规最大接收功率（MAX-RP）。随后，为了利用噪声的彩色特性加上BOB的干扰，提出了基于白色的Max-RP（Max-WFRP），其性能比Max-RP明显增强。为了完全消除Mallory的恶意障碍，提出了一个限制迫使鲍勃（Bob）从马洛里（Mallory）到零的恶意障碍的最大RP。为了进一步提高保密率（SR），通过删除ZF的对抗（ZFC），提出了最大信号到jamming-jamming-plus-noise比率（MAX-SJNR）。我们提出的方法具有封闭形式的表达式。从仿真结果中，四个接收波束形成方法的性能序列增加：Max-RP，具有ZFC和MAX-SJNR $ \ $ \ y MAX MAX-WFRP的MAX-RP。此外，后两种收获的性能在低和中等信噪比的比率区域中以Max-RP和Max-RP的高度提高。
In this paper, we consider a new secure spatial modulation scenario with a full-duplex (FD) malicious attacker Mallory owning eavesdropping capacity, where Mallory works on FD model and transmits a malicious jamming such as artificial noise (AN) to interfere with Bob. To suppress the malicious jamming on Bob from Mallory, a conventional maximum receive power (Max-RP) at Bob is presented firstly. Subsequently, to exploit the colored property of noise plus interference at Bob, a whitening-filter-based Max-RP (Max-WFRP) is proposed with an obvious performance enhancement over Max-RP. To completely remove the malicious jamming from Mallory, a Max-RP with a constraint of forcing the malicious jamming from Mallory to zero at Bob is proposed. To further improve secrecy rate (SR) by removing the ZF contraint (ZFC), the maximum signal-to-jamming-plus-noise ratio (Max-SJNR) is proposed. Our proposed methods have closed-form expressions. From simulation results, the four receive beamforming methods have an increasing order in performance: Max-RP, Max-RP with ZFC and Max-SJNR$\approx$Max-WFRP. Additionally, the latter two harvest a substantial performance gains over Max-RP and Max-RP with ZFC in the low and medium signal-to-noise ratio regions.
