Optimal Number of Transmit Antennas for Secrecy Enhancement in Massive MIMOME Channels
, 2017 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 selects a subset of transmit antennas with the strongest channel gains ...

On Ergodic Secrecy Capacity for Gaussian MISO Wiretap Channels [PDF]
, 2010 A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper each equipped with a single antenna.

New look at secure performance of massive MIMO with low-resolution DACs
ICT Express, 2023 Since the requirement of secure transmission for massive multiple-input–multiple-output (mIMO) is high, we consider a secure massive MIMO system in presence of multiple digital to analog converters (DACs). We deal with complicated performance analysis of

On the Ergodic Secrecy Rate of Massive MIMO Transmission with Partial Legitimate User CSI
2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019 In this paper, we consider the downlink transmission over a single-cell massive multiple-input-multiple-output (MIMO) system in the presence of multiple single-antenna eavesdroppers (massive MIMOME). We concentrate on the practical scenario where partial channel state information (CSI) of legitimate users and no CSI of eavesdroppers are available at ...
