講座內(nèi)容:
Future wireless communications are envisioned to support high mobility environments, such as autonomous cars, unmanned aerial vehicles (UAV), and low-earth-orbit (LEO) satellites. However, the strong multipath and large Doppler features in those environments can impose great challenges for reliable wireless communications and robust sensing. The recently proposed orthogonal time frequency space (OTFS) has provided promising and fundamentally different perspective of waveform design in delay-Doppler (DD) domain in contrast to conventional time-frequency (TF) domain. This talk will introduce the basic concept of OTFS and identify the major technical research problems and challenges. Recent breakthroughs and case studies including transceiver architecture and algorithm designs, channel estimation and data detection techniques, and multiple antenna and multi-user systems are also discussed.
