Sum-Rate Analysis Of Two-Way Multi-Relay Multi-User Mimo Networks With Two-Hop Precoding
2015 INTERNATIONAL CONFERENCE ON ICT CONVERGENCE (ICTC)(2015)
摘要
In this paper, we study a joint source and relay precoding technique for multiuser multi-relay that help to maximize sum rate (SR) for Multiple-Input Multiple-Output (MIMO) link. Here we proposed two-hop precoding technique by implementing Zero-Forcing (ZF) as source precoder and Dirty Paper Coding (DPC) as relay precoder. We show performance by simulating and show that ZF-DPC (i.e., ZF at source and DPC at relay) technique help us to improve sum-rate than using ZF-ZF (i.e., ZF precoder at source and relay).
