Optimizing antenna beamforming with quantum computing
We show how the maximization problem can be rigorously solved by reformulating it as a sequence of quadratic (but non-convex) minimization problems.
Information
We consider beamforming with largescale antenna arrays in which the elements can transmit only in one of a small number of phase-shifts. This creates an NP-hard optimization problem, namely the maximization of the ratio of two Hermitian quadratic forms, with the state vector constrained to the set of allowed phase-shifts. We show how the maximization problem can be rigorously solved by reformulating it as a sequence of quadratic (but non-convex) minimization problems.
