A Modified Structured SAMP Channel Estimation Method for FDD MIMO-OTFS Systems

Orthogonal time frequency space (OTFS) modulation has been proposed to provide users with stable and reliable services in high-mobility scenarios. The sparse representation of channels in OTFS makes it possible to obtain accurate channel state information with a small number of pilots by compressed...
