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…
