RLS Precoding for Massive MIMO Systems with Nonlinear Front-End
Ali Bereyhi, Saba Asaad, Ralf R. Müller +1
To keep massive MIMO systems cost-efficient, power amplifiers with rather small output dynamic ranges are employed. They may distort the transmit signal and degrade the performance…

RLS-Based Detection for Massive Spatial Modulation MIMO
Ali Bereyhi, Saba Asaad, Bernhard Gäde +1
Most detection algorithms in spatial modulation (SM) are formulated as linear regression via the regularized least-squares (RLS) method. In this method, the transmit signal is esti…

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…
