Zak Orthogonal Time Frequency Space (OTFS)

Zak-OTFS is the primary implementation of OTFS, a 2D modulation technique that transforms the information carried in the Delay-Doppler coordinate system. Zak-OTFS is designed to integrate with the 3GPP stack so that scheduling and resource element allocation is unchanged.

It is optimized for wireless communication environments applicable to 6G use cases, such as FR3, NTN and ISAC. Zak-OTFS is supports different channel conditions in real time.
