Orthogonal Time Frequency Space (OTFS)

Special Interest Group


Aim and Scope

Over the past few years, communication technologies for emerging high-mobility applications are much less understood and significantly under-developed. The recently developed OTFS has been recognized globally for its great potential to achieve high-speed and high-reliable communications in a high-mobility environment. While some initial works on the concepts and the implementations of OTFS have been investigated, there are still several challenges and open problems to be addressed.


This SIG is to provide a platform to bring together academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to OTFS.
