DOI: 10.1109/access.2025.3618656
Abstract: Orthogonal time frequency space (OTFS) modulation can effectively combat the multipath and Doppler effects in doubly-selective channels, making it suitable for high-speed mobility scenarios. However, conventional OTFS modulation has a high peak-to-average power ratio (PAPR),… read more here.
