A comprehensive experimental emulation for OTFS waveform RF-Impairments
(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 ...
A novel cyclic prefix configuration for enhanced reliability and spectral efficiency in OTFS systems
(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, ...
Delay-doppler-based key generation using OTFS
(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 ...
