Low complexity peak-to-average power ratio reduction in OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ...
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 ...
NOMA with Index modulation for uplink URLLC through grant-free access
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper proposes non-orthogonal sharing of available resources between latency-critical and latency-tolerant communication for fulfilling tight requirements of ultra-reliable low-latency communication (URLLC) as well ...
OFDM with hybrid number and index modulation
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ...
Fading-aligned OFDM with index modulation for mMTC services
(Elsevier B.V., 2019)
5th generation (5G) of wireless networking is coming with diverse use cases, such as enhanced-Mobile BroadBand (eMBB), Ultra Reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). ...
A hybrid downlink NOMA with OFDM and OFDM-IM for beyond 5G wireless networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
In this paper, a hybrid power domain non-orthogonal multiple accessing (NOMA) scheme by the superposition of orthogonal frequency division multiple accessing (OFDM) and index modulated OFDM (OFDM-IM) technologies is presented ...
Adaptive OFDM-IM for enhancing physical layer security and spectral efficiency of future wireless networks
(Hindawi Limited, 2018)
In this paper, we propose algorithms for enhancing physical layer security and spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (IM) systems. Particularly, different activation ...
