Towards the Asymptotic Sum Capacity of the MIMO Cellular Two-Way Relay Channel
arXiv:1403.6703 · doi:10.1109/TSP.2014.2332971
Abstract
In this paper, we consider the transceiver and relay design for multiple-input multiple-output (MIMO) cellular two-way relay channel (cTWRC), where a multi-antenna base station (BS) exchanges information with multiple multi-antenna mobile stations via a multi-antenna relay station (RS). We propose a novel two-way relaying scheme to approach the sum capacity of the MIMO cTWRC.
