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 ...
Phase rotation approach with mixed-numerology architecture for PAPR reduction in 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2023)
For a wide range of service requirements, the 5G-NR offers significant flexibility based on OFDM with numerous numerologies. However, OFDM is recognized to have a significant disadvantage due to a high PAPR. On the other ...
CSI-Based NOMA for integrated sensing and communication
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2023)
Integrated sensing and communication (ISAC) is a key enabler of beyond fifth-generation networks and a multitude of futuristic applications. However, the coexistence, scheduling and spectrum scarcity issues due to additional ...
Time-frequency warped waveforms for well-contained massive machine type communications
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2023)
This paper proposes a novel time-frequency warped waveform for short symbols, massive machine-type communication (mMTC), and internet of things (IoT) applications. The waveform is composed of asymmetric raised cosine (RC) ...
Waveform design with constellation extension for OFDM dual-functional radar-communications
(Institute of Electrical and Electronics Engineers Inc., 2023)
Orthogonal frequency division multiplexing (OFDM) is widely used and works efficiently for the communication, but emerging applications requires OFDM to be flexible to meet sensing requirements. The time-frequency waveform ...
