Enhanced Multicarrier Techniques for Professional Ad-Hoc and Cell-Based Communications

This deliverable summarizes the final contributions on relaying and coverage extension. In the first part, several results of D7.1 are extended. In particular, the channel frequency selectivity is taken into account and solutions are investigated to cope with it in multi-hop relaying networks as well as in two-way relaying schemes. In the latter case, joint channel and physical layer network decoding is also included in the analysis. Performance evaluations of multi-hop relaying and two-way relaying are then presented in a few specific scenarios using the SONIR simulation tool in the first case, and using a physical layer abstraction method in the second case. Finally, the issue of resource allocation is investigated in an asynchronous decode-and-forward relaying scheme using OFDM or FBMC. A joint subcarrier and power allocation algorithm is proposed to maximize the sumrate taking into account the potential interference resulting from the asynchronism.
