Detection of Spatially Modulated Signals via RLS: Theoretical Bounds and Applications
Ali Bereyhi, Saba Asaad, Bernhard Gäde +2
This paper characterizes the performance of massive multiuser spatial modulation MIMO systems, when a regularized form of the least-squares method is used for detection. For a gene…
Secure Transmission in IRS-Assisted MIMO Systems with Active Eavesdroppers
Ali Bereyhi, Saba Asaad, Ralf R. Müller +2
This work studies secure transmission in intelligent reflecting surfaces (IRS)-assisted MIMO systems when an active eavesdropper is available in the network. We consider a scenario…
A Single-RF Architecture for Multiuser Massive MIMO via Reflecting Surfaces
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
In this work, we propose a new single-RF MIMO architecture which enjoys high scalability and energy-efficiency. The transmitter in this proposal consists of a single RF illuminator…
Efficient Matrix Multiplication: The Sparse Power-of-2 Factorization
Ralf R. Müller, Bernhard Gäde, Ali Bereyhi
We present an algorithm to reduce the computational effort for the multiplication of a given matrix with an unknown column vector. The algorithm decomposes the given matrix into a…
