Compared with orthogonal frequency division multiplexing (OFDM) systems. orthogonal time frequency space systems based on bi-orthogonal frequency division multiplexing (OTFS-BFDM) have lower out-of-band emission (OOBE) and better robustness to high-mobility scenarios. but suffer from a higher peak-to-average ratio (PAPR) in large data packets.
