Energy and spectral efficiency tradeoff in NOMA: Multi-objective evolutionary approaches
(Institute of Electrical and Electronics Engineers Inc., 2020)
Non-orthogonal multiple access (NOMA) deployment in future wireless networks has been recently considered a promising radio access technology to enhance spectral efficiency (SE). However, gain in SE comes always with the ...
Orthogonal frequency division multiplexing with subcarrier gap modulation
(Institute of Electrical and Electronics Engineers Inc., 2020)
A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ...
Dynamic sidelobe multiplexing in beamspace MIMO systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ...
Guard band reduction for 5G and beyond multiple numerologies
(IEEE, 2020)
The existence of inter-numerology interference (INI) is a major drawback for the flexible multi-numerology frame structure proposed for the upcoming fifth generation New Radio (5G-NR). Insertion of a guard band (GB) between ...
