It was show n to offer significant advantages over OFDM in doubly dispersive channels for high mobility wireless communications. The key idea of OTFS is to mode l mobile wireless channels in the delay-Doppler domain\, where a sparse na ture of the geometry of the wireless channel is captured.

Owin g to the inherent high-speed mobile nature of LEO-Sat\, it inevitably lead s to severe Doppler effects\, which greatly affect the reliability of the LEO-Sat links. On the other hand\, existing methods for coping with the Do ppler effect in LEO-sat scenarios generally suffer from high computational complexity and heavy hardware costs. Under this background\, this talk fo cuses on orthogonal time frequency space (OTFS) modulation to enable relia ble LEO-sat communications\, which overcomes the Doppler effect by averagi ng the channel dynamics with modulation information in the delay-Doppler ( DD) domain. In particular\, this talk will discuss the motivations by pres enting the high suitability of OTFS for LEO-sat scenarios\, taking into ac count the Doppler effect characteristics of LEO-Sat communications. Then\, this talk will address the feasibility of OTFS applications for LEO-Sat c ommunications\, and will present recent related works from our group. Fina lly\, a range of promising research opportunities and potential challenges will be provided.\n\n---------------------------------------------------- -\n\nSpeaker(s): Yi Hong \, Zan Li \n\nAgenda: \n8:30 am - 8:35 am Welcome Speech by Prof. Gunes Karabulut Kurt\n\n8:35 am - 9:35 am First Talk by P rof.
