This paper studies cooperative-jamming (CJ)-aided beamforming design under Gaussian channel uncertainties to reduce the secrecy loss due to reception correlation. In light of the difficulty of maximizing the outage-probability-constrained secrecy rate, a novel quality-of-service (QoS)-based optimization is considered. By employing the Bernstein-type inequality to approximate the probabilistic constraints, we seek to maximize the target outage signal-to-noise ratio (SNR) at the destination under transmit power and SNR outage constraints. Simulation results verify the designed CJ-aided beamforming substantially enhances the secrecy from a QoS perspective.

用于相关窃听信道的基于 QoS 的鲁棒协作干扰辅助波束成形

本文研究了高斯信道不确定性下的协作干扰 (CJ) 辅助波束成形设计，以减少由于接收相关性造成的保密损失。鉴于最大化中断概率约束保密率的困难，考虑了一种新颖的基于服务质量（QoS）的优化。通过使用 Bernstein 型不等式来近似概率约束，我们寻求在发射功率和 SNR 中断约束下最大化目的地的目标中断信噪比 (SNR)。仿真结果验证了设计的 CJ 辅助波束成形从 QoS 的角度大大增强了保密性。
