Distributed Tower Top Transceiver Systems for Mobile Communications
Abstract
Over the last few years demand for the capacity and performance in
wireless communications systems has rapidly increased. Wireless 
systems frequently employ electronic beamforming capabilities in 
order to be up to these demands. The target of this project is to
design the usefulness of tower-top based electronics in beamforming 
where the minimum degree of phase offset and good power synchronisation
accuracy should be achieved. The 2x2 array of transmitters 
calibration scheme with the ability to control phase and amplitude is presented.
