Low-PAPR Joint Channel Estimation and Data Detection in ZP-OTFS System
Omid Abbassi Aghda, Mohammad Javad Omidi, Hamid Saeedi-Sourck
Orthogonal Time Frequency Space (OTFS) systems face significant challenges in channel estimation due to high pilot overhead and peak-to-average power ratio (PAPR). To address these…

Superimposed Channel Estimation in OTFS Modulation Using Compressive Sensing
Omid Abbassi Aghda, Mohammad Javad Omidi, Hamid Saeedi-Sourck
Orthogonal time frequency space (OTFS) technique is a two-dimensional modulation method that multiplexes information symbols in the delay-Doppler (DD) domain. OTFS combats high Dop…
