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…

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…

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…
