Abstract

In this paper, we propose a joint analog-digital (AD) beamforming scheme that exploits the mutual coupling effect to further improve the performance of multi-user multiple-input single-output (MU-MISO) systems. We firstly propose a joint AD scheme by iteratively optimizing the beamforming vectors in the digital domain and the load impedances of each antenna element in the analog domain. We further propose a low-complexity decoupled AD scheme, where the mutual coupling exploitation can be efficiently applied upon existing beamformers. The practical implementation of the proposed schemes is also discussed. Numerical results show that the proposed schemes can achieve an improved performance compared to the case with fixed mutual coupling.
