Abstract

  In recent years, the fullduplex twoway relaying system with Massive multiple input multiple output (MIMO) has attracted significant interest because of its performance gain on spectral efficiency and energy efficiency, but it has the problems of residual loop interference (RLI) and pilot contamination. Therefore, this paper considers a Kpair fullduplex twoway relay system, and each user equips single antenna. The relay uses maximumratio combining/maximumratio transmission (MRC/MRT) beamforming to process the signals, and it estimates the channels by only K pilot symbols for 2K users. By theoretical analysis, it is concluded that when very large receive and transmit antenna arrays are used, the RLI due to full duplex and the pilot contamination can be simultaneously cancelled, also the interpair interference and noise vanish. Simulations verify the theoretical results, and show that the energy efficiency and spectral efficiency can increase with the antenna number. Moreover, it is shown that the fullduplex twoway relaying outperforms the halfduplex twoway relaying and the fullduplex oneway relaying in the spectral efficiency when the number of relay receiving/transmitting antenna is up to 160. Therefore, the fullduplex twoway relaying with large antenna arrays has higher communication efficiency than traditional relaying systems.
