An Adaptive Bayesian Framework for Recovery of Sources with Structured Sparsity
Ali Bereyhi, Ralf R. Müller
In oversampled adaptive sensing (OAS), noisy measurements are collected in multiple subframes. The sensing basis in each subframe is adapted according to some posterior information…
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…
PAPR-Limited Precoding in Massive MIMO Systems with Reflect- and Transmit-Array Antennas
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
Conventional hybrid analog-digital architectures for millimeter-wave massive multiple-input multiple-output (MIMO) systems suffer from poor scalability and high implementational co…
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…
A Fair Comparison Between Spatial Modulation and Antenna Selection in Massive MIMO Systems
Bernhard Gäde, Ali Bereyhi, Saba Asaad +1
Both antenna selection and spatial modulation allow for low-complexity MIMO transmitters when the number of RF chains is much lower than the number of transmit antennas. In this ma…
