Abstract

This study examines the non-orthogonal multiple access (NOMA) system that is modulated with orthogonal timefrequency- space (OTFS), which is a potential waveform candidate that is frequently used in sixth-generation (6G) wireless communication networks and is shown to improve performance in high mobility scenarios. In the proposed OTFS modulated NOMA system, bit error rate performance for near and far users is presented with the help of the message passing detection algorithm.
