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, ... -
OTFS-FMCW waveform design for low complexity joint sensing and communication
Zegrar, Salah Eddine; Rafique, Saira; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2022)Joint sensing and communication (JSAC) systems are becoming attractive technologies since they can map the radio environment while performing communication using the same frequency bands. This is achieved by radar signal ... -
Precoding based cross-tier interference mitigation in centralized-RAN
Zegrar, Salah Eddine; Duranay, Ahmet Enes; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)This letter considers a two-tier downlink interference problem as a case of study, where macrocell user equipment (UE) shares the same frequency band with femtocell UE and suffers from severe cross-tier interference. Power ... -
Reconfigurable intelligent surface (RIS): Eigenvalue decomposition-based separate channel estimation
Zegrar, Salah Eddine; Afeef, Liza; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2021)Reconfigurable intelligent surface (RIS) has recently drawn significant attention in wireless communication technologies. However, identifying, modeling, and estimating the RIS channel in multiple-input multiple-output ... -
Signal domain physical modification for PLS
Zegrar, Salah Eddine; Naeem, Ahmed; Furqan, Haji M.; Arslan, Hüseyin (Institution of Engineering and Technology, 2023)...
