In this paper, the multi-pair two-way relaying multi-input multiple-output system is considered, in which K-pair users exchange information within communication pair, by a shared amplify-and-forward relay station equipped with N antennas, N ≫ 2K. Considering two kinds of receiver, i.e., maximum-ratio combining receiver and zero-forcing receiver, we investigate the achievable rate performance in Ricean...
This paper studies incremental relay strategies for a two-user Gaussian relay-interference channel with an in-band-reception and out-of-band-transmission relay, where the link between the relay and the two receivers is modelled as a degraded broadcast channel. It is shown that generalized hash-and-forward (GHF) can achieve the capacity region of this channel to within a constant number of bits in...
