Layered Orthogonal Frequency Division Multiplexing With Index Modulation

IEEE Systems Journal, 2019
In this paper, we propose a novel scheme termed layered orthogonal frequency division multiplexing with index modulation (L-OFDM-IM) to increase the spectral efficiency (SE) of OFDM-IM systems.

Spectrally Efficient Frequency Division Multiplexing With Index-Modulated Non-Orthogonal Subcarriers

IEEE Wireless Communications Letters, 2019
In this letter, we propose a novel index-modulated non-orthogonal spectrally efficient frequency-division multiplexing (SEFDM) scheme, in order to attain a higher bandwidth efficiency than the conventional orthogonal frequency-division multiplexing (OFDM)

Full-Duplex Relay-Assisted Orthogonal Frequency-Division Multiplexing With Index Modulation

IEEE Systems Journal, 2019
In this paper, we propose a full-duplex relay-assisted orthogonal frequency-division multiplexing (OFDM) with index modulation system, in which a complete transmission from source to destination is forwarded by a full-duplex decode-and-forward relay.
