Coexistence of Communication Systems Based on Enhanced Multi-Carrier Waveforms with Legacy OFDM Networks (2017)
Abstract / truncated to 115 words
Future wireless networks are envisioned to accommodate the heterogeneous needs of entirely different systems. New services obeying various constraints will coexist with legacy cellular users in the same frequency band. This coexistence is hardly achievable with OFDM, the physical layer used by current systems, because of its poor spectral containment. Thus, a myriad of multi-carrier waveforms with enhanced spectral localization have been proposed for future wireless devices. In this thesis, we investigate the coexistence of new systems based on these waveforms with legacy OFDM users. We provide the first theoretical and experimental analysis of the inter-system interference that arises in those scenarii. Then, we apply this analysis to evaluate the merits of different enhanced waveforms ... toggle 11 keywordscoexistence – 5G – OFDM – filter banks – FBMC – OFDM/OQAM – GFDM – FMT – FBMC-PAM – COQAM – interference analysis.
