TLDR
Among the possible subcarrier mapping approaches, it is found that localizedFDMA (LFDMA) with channel-dependent scheduling (CDS) results in higher throughput than interleaved FDMA (JFDMA), however, the PARR performance of IFDMA is better than that of LFDMA.

Time Spread-Windowed OFDM for Spectral Efficiency Improvement

TL;DR: This letter proposes a new orthogonal frequency division multiplexing (OFDM)-based waveform, called time spread-windowed OFDM (TS-W-OFDM), which applies a windowing procedure to improve spectral efficiency and a time spreading method to create a block signal structure.

MMSE beamforming for SC-FDMA transmission over MIMO ISI channels

TL;DR: It is proved that for SC-FDMA transmission in both cases eigenbeamforming, diagonalizing the overall channel, together with a nonuniform power distribution is the optimum beamforming strategy.

Transmission techniques for digital terrestrial TV broadcasting

TL;DR: 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.

Fair multiuser channel allocation for OFDMA networks using Nash bargaining solutions and coalitions

TL;DR: The proposed algorithms not only provide fair resource allocation among users, but also have a comparable overall system rate with the scheme maximizing the total rate without considering fairness, and have much higher rates than that of the scheme with max-min fairness.
