MIMO millimeter-wave channel estimation using coalitional games

Abstract

In millimeter-wave massive multiple input multiple output (MIMO) antenna systems, channel estimation is a crucial component. In this paper, we propose a virtual channel representation channel estimation method us-ing out-of-band spatial information to reduce training overheads and a cooperative channel allocation method based on coalitional game framework. The proposed cooperative chan-nel allocation method enhances throughput performance in mm-wave small cell networks.
