Source and Physical-Layer Network Coding for Correlated Two-Way Relaying
, 2016 In this paper, we study a half-duplex two-way relay channel (TWRC) with correlated sources exchanging bidirectional information. In the case, when both sources have the knowledge of correlation statistics, a source compression with physical-layer network
