Optimised Constellation Prerotation for 3-Terminal 1-Relay Network with Wireless Network Coding

Popis výsledku v původním jazyce

Wireless (Physical-Layer) Network Coding (WNC) is an interference harnessing physical-layer concept combining network coding principles and broadcast nature of the wireless medium. Significant capacity gains of WNC were shown in a wireless 2-Way Relay Channel (2-WRC). Extension of WNC to more complicated network topologies potentially offers even larger gains than in the 2-WRC. However, such an extension is generally non-trivial. In this paper, we show that it is feasible to achieve additional considerable capacity gains in comparison to bidirectional relaying approach in a three-terminal onerelay network. We focus on the constellation design for its uplink (Multiple Access Channel (MAC) stage). The throughput maximisation is achieved by an optimised prerotation of source constellations, effectively reducing a number of required MAC stages.
