Robust Secure Beamforming for Multibeam Satellite Communication Systems
IEEE Transactions on Vehicular Technology(2019)
摘要
This paper proposes a robust beamforming (BF) scheme to enhance the physical layer security (PLS) of a multibeam satellite system operating at Ka band. By considering the effects of beam gain, path loss, and rain attenuation, we first formulate a constrained optimization problem to maximize the minimal achievable secrecy rate of multiuser under the assumption of imperfect eavesdropping channel and...
