IEEE OJVT Special Issue on Orthogonal Time Frequency Space (OTFS)
Orthogonal Time Frequency Space (OTFS) modulation and Delay-Doppler (DD) signal processing is an emerging technology aimed at addressing challenges in hostile wireless communication environments. These environments include scenarios like mobile communications on aircraft, satellite communications, vehicle-to-vehicle communications, and underwater acoustic communications, where traditional modulation techniques like OFDM struggle due to severe delay and Doppler effects. OTFS modulation operates in the DD domain instead of the conventional time-frequency domain, offering advantages such as enhanced resilience against Doppler and delay effects, lower peak-to-average power ratio, reduced signaling overhead, and robustness against synchronization errors. It is considered a promising technology for 6G wireless systems.
We are very happy to have a few leading researchers in this research area, namely Qin Tao (Hangzhou Normal University), Shuangyang Li (Technical University of Berlin), Weijie Yuan (Southern University of Science and Techonology), Slawomir Stanczak (Fraunhofer Heinrich Hertz Institute), Emanuele Viterbo (Monash University), and Xianbin Wang (Western University), to publish a special issue in our journal, IEEE Open Journal of Vehicular Technology, that emphasizes the importance of OTFS modulation and DD signal processing in advancing wireless communication technologies, particularly for 6G systems, and encourages further research in this field.
The special issue features five articles covering various aspects of OTFS:
