Robust Beamforming Design for Sum Secrecy Rate Optimization in MU-MISO Networks
Robust Beamforming Design for Sum Secrecy Rate Optimization in MU-MISO Networks
This paper studies the beamforming design problem of a multiuser downlink network, assuming imperfect channel state information known to the base station. In this scenario, the base station is equipped with multiple antennas, and each user is wiretapped by a specific eavesdropper where each user or eavesdropper is equipped with …
