OTFS with Multicarrier MIMO in Fading Scenarios

Abstract

Recently, there has been increased awareness of the reliability of Orthogonal Time Frequency Space (OTFS) modulation as a method for wireless communication, especially in high-mobility and multipath situations. This work analyses the performance of OTFS under different fading conditions and investigates its integration with multicarrier Multiple-Input Multiple-Output (MIMO) systems. The study exhibits improved reliability and spectrum efficiency by utilising the advantages of multicarrier transmission and the resilience of OTFS, providing insights into its application for next-generation communication systems.
