Abstract—The paper addresses wireless the 2-Way Relay Channel (2-WRC) system with a Hierarchical Decode and Forward strategy. This strategy uses a Hierarchical eXclusive Code (HX...
Abstract--A multiple access channel and a point-to-point channel sharing the same medium for communications are considered. We obtain an outer bound for the capacity region of this...
The capacity regions are investigated for two relay broadcast channels (RBCs), where relay links are incorporated into two-user broadcast channels to support user cooperation. In t...
The sum-capacity is studied for a K-user physically degraded Gaussian multiaccess relay channel (MARC). Decodeand-forward (DF) is shown to achieve the sum-capacity and capacity reg...
