QoS-Based Source and Relay Secure Optimization Design with Presence of Channel Uncertainty
Meng Zhang, Jian Huang, Hui Ming Yu, Hanwen Luo, Wen Chen · IEEE Communications Letters · 2013
In this letter, we study relay-aided networks with presence of single eavesdropper. We provide joint beamforming design of the source and relay that can minimize the overall power consumption while satisfying our predefined quality-of-service (QoS) requirements. Additionally, we investigate the case that the channel between relay and eavesdropper suffers from channel uncertainty. Finally, simulation results are provided to verify the effectiveness of our algorithm.
