Coordinated Hybrid Precoding for Interference Exploitation in Heterogeneous Networks
Ganapati Hegde, Christos Masouros, Marius Pesavento
We consider a downlink multiuser massive MIMO system comprising multiple heterogeneous base stations with hybrid precoding architectures. To enhance the energy efficiency of the ne…

Interference Exploitation-based Hybrid Precoding with Robustness Against Phase Errors
Ganapati Hegde, Christos Masouros, Marius Pesavento
Hybrid analog-digital precoding significantly reduces the hardware costs in massive MIMO transceivers when compared to fully-digital precoding at the expense of increased transmit…

Joint Antenna Selection and Phase-Only Beamforming Using Mixed-Integer Nonlinear Programming
Tobias Fischer, Ganapati Hegde, Frederic Matter +3
In this paper, we consider the problem of joint antenna selection and analog beamformer design in downlink single-group multicast networks. Our objective is to reduce the hardware…
