Models and optimization techniques for discrete beamforming

Abstract

Beamforming summarizes techniques to adapt the radiation pattern of an antenna array. If each element of such an array can be adjusted according to a finite set of control parameters only then adapting the radiation pattern is called discrete beamforming and, depending on an appropriate goal, leads to a difficult discrete or mixed-integer optimization problem. In this talk we will present basic beamforming approaches and concentrate on discrete receive beamforming.
