On the Study of Half-Duplex Two-Way Relaying Based on Network Coding
Jin Hong Fan · Applied Mechanics and Materials · 2013
A novel scheme based on detection is proposed for half-duplex two-way relay system in this paper. Multi-input multi-output and network coding technique are applied in the relay. The proposed method employs detection in this system when the relay and two stations receive signal. Theoretical and simulative analyses of the protocol performance under the assumption of a binary symmetric relay channel model are carried out. The zero-forcing detection and maximum likelihood detection are respectively used. The simulation results show that the new scheme facilitates more reliable transmission and higher information transmission rate.
