On Robustness of Massive MIMO Systems Against Passive Eavesdropping under Antenna Selection
Ali Bereyhi, Saba Asaad, Ralf R. Müller +2
In massive MIMO wiretap settings, the base station can significantly suppress eavesdroppers by narrow beamforming toward legitimate terminals. Numerical investigations show that by…

Optimal Transmit Antenna Selection for Massive MIMO Wiretap Channels
Saba Asaad, Ali Bereyhi, Amir M. Rabiei +2
In this paper, we study the impacts of transmit antenna selection on the secrecy performance of massive MIMO systems. We consider a wiretap setting in which a fixed number of trans…

Optimal Number of Transmit Antennas for Secrecy Enhancement in Massive MIMOME Channels
Saba Asaad, Ali Bereyhi, Ralf R. Müller +2
This paper studies the impact of transmit antenna selection on the secrecy performance of massive MIMO wiretap channels. We consider a scenario in which a multi-antenna transmitter…
