Distributed limited feedback beamforming based on game theory in multiple-input multiple-output ad hoc networks

In this study, the authors propose a distributed beamforming scheme with limited feedback in multiple-input multiple-output ad hoc networks. In the proposed scheme, all transmitting and receiving node pairs sharing the same frequency band perform an iterative sequential beamformer update in a distributed way. According to the authors analysis using game theory, the proposed iterative sequential beamformer update is modified to converge to the generalised Nash equilibrium. The performance of the proposed scheme is also demonstrated by computer simulation.
