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 ...
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 ...
