We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate som...

This paper presents an outage performance of multiple access relay channel (MARC) for decode-and-forward (DF) relay and amplify-and-forward (AF) relay selection. We consider the multiple-access relay channel with two source nodes, one relay node and one destination node. In MARC, multiple sources transmit to a common destination simultaneously with the assistance of a single relay. In a relayin...

We study the discrete, memoryless multiple-access channel with two independent sources, two relays and a single destination. We refer to this configuration as the multiple-access channel with multiple relays (MACMR), which is a generalization of the multiple-access relay channel (MARC) model obtained by adding a relay node. We present inner and outer bounds on the capacity region of the MACMR. ...

In this paper, we model a specific relay channel named relay multiple access channel (RMAC) aiming at providing a clue to select the relay node in multiple access channels such as the uplink of cellular communication system. In this channel, the relay node not only aids to send the information of the source but also sends its private message to the destination. We derive the achievable rate reg...

In this paper, we obtain a general achievable rate region and some certain capacity theorems for multiple-access relay channel (MARC), using decode and forward (DAF) strategy at the relay, superposition coding at the transmitters. Our general rate region (i) generalizes the achievability part of Slepian-Wolf multiple-access capacity theorem to the MARC, (ii) extends the Cover-El Gamal best achi...
