Decode-and-Forward Design of Signal Space Alignment for Network Coding on Asymmetric MIMO Y Channels
Qing An Huang, Yingmin Wang · 2013
In this paper, we study the multi-pair two-way relay (TWR) system, in which not all users utilize the identical modulation scheme. Signal space alignment for network coding(SSA-NC) is used to realize efficient communication among multiuser(MU). The paired signals are aligned and decoded-and-forwarded(DF) at the relay. Considering different modulation schemes utilized, we propose a novel DF strategy design and decoding rules. Monte Carlo simulation results demonstrate the advantage of the proposed approach.
