Antenna Placement Designs for Distributed Antenna Systems with Multiple-Antenna Ports [PDF]

open access: yes2012 IEEE Vehicular Technology Conference (VTC Fall), 2012
In this paper, we optimize antenna locations for a distributed antenna system (DAS) with distributed antenna (DA) ports equipped with multiple antennas under per-DA port power constraint. Maximum ratio transmission and scaled zero-forcing beamforming are employed for single-user and multi-user DAS, respectively.
