Waveform-domain NOMA: The future of multiple access
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper introduces a novel non-orthogonal multiple access (NOMA) concept named waveform-domain NOMA, which proposes the coexistence of different waveforms in the same resource element (RE). Regarding the demands of each ...
Application-based coexistence of different waveforms on non-orthogonal multiple access
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
In the study, the coexistence of different waveform structures on the same resource element is studied under the theory of non-orthogonal multiple access (NOMA). This study introduces a paradigm-shift on NOMA towards the ...
Blind numerology identification for mixed numerologies
