英文摘要	An estimate-and-forward (EF) scheme for single-input single-output (SISO) and multiple-input multiple-output (MEMO) full-duplex two-way relay networks is proposed and analyzed. The relay estimates the received signal from two terminal nodes by a minimum mean squared error (MMSE) estimation and forwards a scaled version of the MMSE estimate to the destination. The proposed EF outperforms conventional amplify -and-forward (AF) and decode-and-forward (DF) across all signal-to-noise ratio (SNR) region. Because its computational complexity is high for relays with a large number of antennas (large MIMO) and/or high order constellations, an approximate EF scheme, called list EF, are thus proposed to reduce the computational complexity. The proposed list EF computes a candidate list for the MMSE estimate by using a sphere decoder, and it approaches the performance of the exact EF relay at a negligible performance loss. The proposed forwarding approach also could be used to other relay networks, such as half-duplex, one-way or massive MIMO relay networks.; National Natural Science Foundation of China [61501461, 61471269, 61622101, 61571020]; National 973 Project [2013CB336700]; National 863 Project [SS2015AA011306]; National Science Foundation [CNS-1343189, ECCS-1232305]; Early Career Development Award of SK-LMCCS [Y3S9021F34]; SCI(E); 中国科学引文数据库(CSCD); ARTICLE; 4; 65-72; 14
