Retrospective Interference Regeneration Schemes for Relay-Aided K-user MIMO Downlink Networks

Abstract: As a novel method to increase channel capacity of networks, interference alignment (IA) technique has attracted wide attention in fifth-generation wireless networks (5G). However, when it is applied in interference networks, the problem about information delay arises which has not been noticed yet. In this paper, we first propose degree of delay (DoD) to quantify the issue of information delay, and characterize DoD for three typical transmission schemes, i.e., TDMA, beamforming based TDMA (BD-TDMA) and retrosp… Show more
