Orthogonal Time Frequency Space Modulation (OTFS) for Reliable High-mobility Communications

Dalian, China|10-12 August 2023



Over the past decades, wireless technologies with reliable data transmissions and precise sensing ability in hostile environments are much less understood and significantly under-developed. The delay-Doppler (DD) domain waveform, e.g., orthogonal time frequency space (OTFS), has been recognized globally for its great potential to achieve high-reliable communications and robust sensing performance under various channel conditions.

OTFS modulates the information directly in the DD domain rather than the classic time-frequency (TF) domain for OFDM. The DD domain multiplexing changes the way of interaction between information symbols and wireless channels, which provides the benefit of high Doppler and Doppler-resilience against the highly dynamic wireless channels in hostile environments as well as a direct reflection of key sensing parameters. Besides, the two-dimensional (2D) spreading of information symbols from the DD domain to the TF domain allows each DD domain symbol to experience the full TF channel over a frame, resulting in the potential of achieving full channel diversity. Unfortunately, existing DD domain communication schemes were mainly designed based on the overlay with the classic OFDM modulation, where the essence of DD domain signal processing and how it will guild the DD domain waveform designs for communications and sensing purposes are less understood.

As a new paradigm, using DD domain for communications will introduce new critical challenges for transceiver architecture and algorithm designs. To fully unleash the potential of DD domain communications, challenging fundamental research problems and many practical design issues must be addressed, including channel estimation, detection techniques, and multi-user multiple-antenna systems design. This workshop aims at bringing together academic and industrial researchers to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to DD communications, sensing, and ISAC.
