Orthogonal Time Frequency Space Modulation in 6G Era

High speed and ultra-reliable communications for a wide range of emerging mobile applications, including online gaming, vehicle-to-everything (V2X), and low-earth-orbit satellites (LEOS) communications are expected to be provided in the 6G era. The widely adopted orthogonal frequency division multiplexing (OFDM) modulation in the current 5G networks may fail to work due to the severe channel Doppler in high mobility scenarios. Recently, a new two-dimensional (2D) modulation scheme referred to as orthogonal time frequency space (OTFS) was proposed, where the information symbols are multiplexed in the Delay-Doppler (DD) domain rather than the time-frequency (TF) domain as the traditional modulation techniques. The DD domain multiplexing provides the possibility to embrace the channel impairments, such as delay and Doppler shifts, and to provide the benefits of delay- and Doppler-resilience. More importantly, OTFS enjoys the full time-frequency diversity of the channel, which is the key to provide reliable communications. Relying on 2D orthogonal transform, OTFS modulation effectively represents the time-variant channel into an effective 2D time-invariant channel in the DD domain, where attractive properties, such as separability, compactness, stability, and possibly sparsity, exhibit and are potential to be exploited for OTFS system designs. In addition to several benefits in communications, the radar sensing also focuses on the delay-Doppler (DD) domain parameters, which provides the possibility for unified framework design for the integrated sensing and communications.

As a new waveform, OTFS introduces new critical challenges for transceiver architecture and algorithm designs. To fully unleash the potential of OTFS, challenging fundamental research problems and many practical design issues must be addressed, including code design, channel estimation, detection techniques, and multiple antenna and multiple user systems design.

The main goal of this special issue is to attract academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to OTFS.
