Common CP-OFDM transceiver design for low-complexity frequency domain equalization
Zegrar, Salah Eddine; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)Common cyclic prefix-orthogonal frequency-division multiplexing (CCP-OFDM) groups multiple OFDM symbols and uses one CP to protect them in slow time-variant channels. However, due to this particular design of CCP-OFDM ... -
A comprehensive experimental emulation for OTFS waveform RF-Impairments
Abushattal, Abdelrahman; Zegrar, Salah Eddine; Yazgan, Ayhan; Arslan, Hüseyin (MDPI, 2023)The orthogonal time-frequency space (OTFS) waveform exceeds the challenges that face orthogonal frequency division multiplexing (OFDM) in a high-mobility environment with high time-frequency dispersive channels. Since radio ... -
Delay-doppler-based key generation using OTFS
Solaija, Muhammad Sohaib J.; Zegrar, Salah Eddine; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2023)Key generation for secure communication is challenging in high-mobility scenarios due to the low coherence time. This is further exacerbated in frequency-division duplex systems due to the non-reciprocal wireless channel ... -
Flexible physical layer security for joint data and pilots in future wireless networks
Zegrar, Salah Eddine; Furqan, Haji Muhammad; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)In this work, novel physical layer security (PLS) schemes are proposed for orthogonal frequency-division multiplexing (OFDM) to secure both data and pilots in multiple-input multiple-output (MIMO) systems. The majority of ... -
A novel cyclic prefix configuration for enhanced reliability and spectral efficiency in OTFS systems
Zegrar, Salah Eddine; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2023)In practical transmission, orthogonal time-frequency-space (OTFS) is implemented using different prefix configurations including reduced-cyclic prefix (RCP) and full-CP (FCP). This letter presents a novel OTFS structure, ...
