Classifications and applications of physical layer security techniques for confidentiality: a comprehensive survey
(IEEE, 2019)
Physical layer security (PLS) has emerged as a new
concept and powerful alternative that can complement and may
even replace encryption-based approaches, which entail many
hurdles and practical problems for future ...
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 ...
OFDM with hybrid number and Index modulation
(IEEE Access, 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 ...
