Robustness of Low-Complexity Massive MIMO Architectures Against Passive Eavesdropping
Ali Bereyhi, Saba Asaad, Ralf R. Müller +3
Invoking large transmit antenna arrays, massive MIMO wiretap settings are capable of suppressing passive eavesdroppers via narrow beamforming towards legitimate terminals. This imp…
Secure Regularized Zero Forcing for Multiuser MIMOME Channels
Saba Asaad, Ali Bereyhi, Ralf R. Müller +1
This paper proposes a new linear precoding scheme for downlink transmission in MIMOME channels, referred to as secure regularized zero forcing. The scheme modifies regularized zero…
Joint User Selection and Precoding in Multiuser MIMO Systems via Group LASSO
Saba Asaad, Ali Bereyhi, Ralf R. Muller +1
Joint user selection and precoding in multiuser MIMO settings can be interpreted as group sparse recovery in linear models. In this problem, a signal with group sparsity is to be r…
Private Authentication with Physical Identifiers Through Broadcast Channel Measurements
Onur Günlü, Rafael F. Schaefer, Gerhard Kramer
A basic model for key agreement with biometric or physical identifiers is extended to include measurements of a hidden source through a general broadcast channel (BC). An inner bou…
Deep Learning for Channel Coding via Neural Mutual Information Estimation
Rick Fritschek, Rafael F. Schaefer, Gerhard Wunder
End-to-end deep learning for communication systems, i.e., systems whose encoder and decoder are learned, has attracted significant interest recently, due to its performance which c…
On the Optimality of D2D Coded Caching with Uncoded Cache Placement and One-shot Delivery
Çağkan Yapar, Kai Wan, Rafael F. Schaefer +1
We consider a cache-aided wireless device-to-device (D2D) network of the type introduced by Ji, Caire, and Molisch [1], where the placement phase is orchestrated by a central serve…
