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 ...
A novel delay-doppler-based channel estimation method in doubly-dispersive ocdm systems
(2024)
Orthogonal chirp division multiplexing (OCDM) has recently emerged as a new candidate for the 6G waveform. In high-mobility wireless channels, the inseparability of the data symbols in both time and frequency domains makes ...
Optimal handover optimization in future mobile heterogeneous network using integrated weighted and fuzzy logic models
(2024)
High mobility travelling trains and drones connected via ultra-dense mobile networks may lead to frequent handovers (HOs). As a consequence, this could arise the mobility problems of the serving network such as handover ...
A novel HARQ design for RSMA networks
