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 ...
New physical layer key generation dimensions: subcarrier indices/positions-based key generation
(IEEE Communications Letters, 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
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 ...
Modified MU-STBC with round transmission for improving the date rate and reliability of future 6G and beyond wireless networks
(2023)
In this study, we present a novel multi-user scheme in which space-time block coding (STBC) is exploited for transmitting data in two rounds in a multiple-input multiple-output (MIMO) fashion while orthogonal frequency ...
OFDM-subcarrier power modulation with two dimensional signal constellations
(2019 Innovations in Intelligent Systems and Applications Conference (ASYU), 2019)
An original modulation technique has been recently proposed for wireless communication systems known as OFDM- SPM (OFDM with Subcarrier Power Modulation). This technique utilizes a characteristic of the subcarriers of the ...
