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 Nonlinear LSE Precoders with Applications to Transmit Antenna Selection
Ali Bereyhi, Mohammad Ali Sedaghat, Ralf R. Müller
This paper studies the large-system performance of Least Square Error (LSE) precoders which~minimize~the~input-output distortion over an arbitrary support subject to a general pena…
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…
A New Class of Nonlinear Precoders for Hardware Efficient Massive MIMO Systems
Mohammad A. Sedaghat, Ali Bereyhi, Ralf R. Müller
A general class of nonlinear Least Square Error (LSE) precoders in multi-user multiple-input multiple-output systems is analyzed using the replica method from statistical mechanics…
Replica Symmetry Breaking in Compressive Sensing
Ali Bereyhi, Ralf Müller, Hermann Schulz-Baldes
For noisy compressive sensing systems, the asymptotic distortion with respect to an arbitrary distortion function is determined when a general class of least-square based reconstru…
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…
