We consider a multi-link and multi-input-multi-output (MIMO) interference system in which each link wishes to minimize its own power by choosing its own signal vector subject to an information theoretic quality-of-service (QoS) requirement. Our setup leads to a multi-link game, referred to as a ldquopower gamerdquo, in which the feasible strategy set of an individual link depends on the strategies...
We consider a multi-link MIMO interference system in which each link wishes to maximize its own mutual information by choosing its own signal vector, which leads to a multi-player game. We show the existence of a Nash equilibrium and obtain sufficient conditions for the uniqueness of equilibrium. We consider two decentralized link adjustment algorithms called best-response process (a.k.a. iterative...
In Z. Zhang et al., (2003) - M. Rezk et al., (2005), a hybrid beamforming algorithm utilizing a subset of array elements according to receive signal strength has been proposed. The algorithm utilizes a smart switch which selects a subset of antennas that receive the signals with higher strength. Then a beamforming algorithm is applied to calculate the weights for the selected antennas. Since earlier...
