This letter designs a robust beamformer for correlated multiple-input-single-output wiretap channels with multiple noncollaborating passive single-antenna eavesdroppers under channel uncertainty. Assuming that the source has only partial main channel information and statistical wiretap channel information, we seek to maximize the secrecy rate under the transmit power and secrecy outage constraints. To enhance security, the correlation between the main and wiretap channels, as a resource, is fully utilized to optimize the secure beamformer. Simulation results show that the secrecy rate is improved significantly under the transmit power and secrecy outage constraints.

信道不确定性下相关 MISO 窃听信道的稳健波束成形设计

这封信为相关的多输入单输出窃听通道设计了一种强大的波束形成器,在通道不确定性下具有多个非协作的无源单天线窃听器。假设源只有部分主信道信息和统计窃听信道信息,我们寻求在发射功率和保密中断约束下最大化保密率。为了增强安全性,充分利用主通道和窃听通道之间的相关性作为资源来优化安全波束形成器。仿真结果表明,在发射功率和保密中断约束下,保密率得到显着提高。
