OTFS-SCMA: A Code-Domain NOMA Approach for Orthogonal Time Frequency Space Modulation

Orthogonal time frequency space (OTFS) modulation is a two-dimensional (2-D) modulation technique that has the potential to overcome the challenges faced by orthogonal frequency division multiplexing (OFDM) in high Doppler environments. The performance of OTFS in a multi-user scenario with orthogona...
