Channel Estimation and Equalization for CP-OFDM-based OTFS in Fractional Doppler Channels
Noriyuki Hashimoto, Noboru Osawa, Kosuke Yamazaki +1
Orthogonal time frequency and space (OTFS) modulation is a promising technology that satisfies high Doppler requirements for future mobile systems. OTFS modulation encodes informat…
