TLDR
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency- domain equalization, and introduces coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving.Abstract:
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency-domain equalization. The carrier synchronisation issue is dealt with before the authors introduce coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving. >read more

Energy-efficient cooperative single-carrier frequency-division multiple-access
TL;DR: This work proposes an efficient subband-based AF scheme, which is benchmarked against the conventional AF regime in the context of both the SDR and SSR topologies, and two first-hop-quality-aware (FHQA) joint dynamic resource allocation (DRA) schemes for opportunistic relaying (OR) based SCFDMA uplink, which beneficially combines channel- quality-aware subband allocation with efficient relay selection.
