Low-Complexity Oversampled OTFS Receivers With Reduced Overhead

Low-Complexity Oversampled OTFS Receivers With Reduced Overhead

Orthogonal Time Frequency Space (OTFS) modulation enables reliable communication in fast time-varying, frequency-selective channels. It is a delay-Doppler (DD) domain modulation that models the information symbols and the channel in the DD domain. This paper considers a pulse-shaped OTFS system with...
