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…
Asymptotics of Transmit Antenna Selection: Impact of Multiple Receive Antennas
Saba Asaad, Ali Bereyhi, Ralf R. Müller +1
Consider a fading Gaussian MIMO channel with transmit and receive antennas. The transmitter selects antennas corresponding to the stron…
Asymptotic Performance Analysis of Spatially Reconfigurable Antenna Arrays
Saba Asaad, Ali Bereyhi, Mohammad Ali Sedaghat +2
A spatially reconfigurable antenna arrays consists of an antenna array of finite length and fixed geometry which is displaced within a given area. Using these reconfigurable compon…
Nonlinear Precoders for Massive MIMO Systems with General Constraints
Ali Bereyhi, Mohammad Ali Sedaghat, Saba Asaad +1
We introduce a class of nonlinear least square error precoders with a general penalty function for multiuser massive MIMO systems. The generality of the penalty function allows us…
