Bayesian-based Symbol Detector for Orthogonal Time Frequency Space Modulation Systems
Xinwei Qu, Alva Kosasih, Wibowo Hardjawana +2
Recently, the orthogonal time frequency space (OTFS) modulation is proposed for 6G wireless system to deal with high Doppler spread. The high Doppler spread happens when the transm…
