CP-less OFDM with alignment signals for enhancing spectral efficiency, reducing latency, and improving PHY security of 5G services
(IEEE Access, 2018)
Although orthogonal frequency-division multiplexing (OFDM) is a widely accepted waveform
in many standards and is expected to keep its dominance in future 5G systems with various types of
parameterized waveforms, its ...
Modulation options for OFDM-based waveforms: classification, comparison, and future directions
(IEEE, 2019)
This paper provides a comparative study on the performance of different modulation options
for orthogonal frequency division multiplexing (OFDM) in terms of their spectral efficiency, reliability,
peak-to-average power ...
Orthogonal frequency division multiplexing with subcarrier gap modulation
(IEEE 31st PIMRC'20 - Workshop on Waveform Design for Beyond 5G Communications, 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 ...
