摘要

我们考虑具有多个窃听器的MISO窃听通道。在信道不确定性条件下，在信噪比约束下，联合设计波束形成器和人工噪声的协方差，使发射功率最小。我们的设计问题是通过使用半定程序来解决的，该程序可以进行数值求解。仿真结果显示了信道不确定性对发射功率的影响。

Robust beamformer and artificial noises for MISO wiretap channels with multiple eavesdroppers

We consider MISO wiretap channels with multiple eavesdroppers. Under the deterministic channel uncertainties, the beamformer and the covariance of the artificial noise are jointly designed to minimize the transmit power subject to SINR constraints. Our design problems are resolved by using a semidefinite program, which can be numerically solved. Simulation results are provided to see the effects of channel uncertainties on the transmit power.
