We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other through a relay. The relays use network coding to simultaneously transmit the signals corresponding to the pairs they are assigned to. We propose two relay assignment schemes. One scheme...
In this paper, we consider cooperative networks comprising multiple simultaneous transmitting source-destination pairs. Specifically, we propose two relay assignment schemes whereby one relay is assigned to one pair at any given time. It is assumed that the number of relays equals or exceeds the number of pairs. This assumption is practical because in future wireless networks, any node in the network...
