A&M based fractional delay and Doppler channel estimation in OTFS

Orthogonal time frequency space (OTFS) modulation is a candidate for low-density high-mobility communication (LDHMC) use case in sixth generation (6G) due to its robustness against Doppler effects. This paper presents a low-complexity channel estimation method based on the A&M fr...
