Abstract

This article presents a beam distribution methodology adapted to direct radiating arrays with hybrid beamforming techniques conceived to maximize the throughput of telecommunication systems. The optimal multiple beam coverage is achieved when the beam centers are superimposed with null positions of the other beams. An optimal spectral efficiency is achieved on links established at the vicinity of the beam centers, and is similar to that achieved when precoding is implemented in order to mitigate co-channel interferences.
