Low-PAPR Pilot-Aided Deep Channel Estimation for OTFS Systems With HPA Nonlinearity

High-power amplifier (HPA) nonlinearity distorts orthogonal time frequency space (OTFS) signals and degrades pilot observations, thereby posing significant challenges to channel estimation, particularly under severe Doppler shifts in high-mobility scenarios. This letter proposes a robust OTFS channel estimation method...
