论文摘要
本教程的前两个部分关于正交时间频率空间（OTF）调制已讨论了延迟多普勒（DD）域通信的基本原理以及一些用于收发器设计的高级技术。在这封信中，我们将介绍一个基于OTFS的集成传感和通信（ISAC）系统，该系统被认为是下一代无线通信中的一种启示技术。特别是，我们说明了OTFS-ISAC系统的感应和通信模型。接下来，我们表明，从时间不变的DD通道中受益时，感应参数可用于推断通信通道，从而导致有效的传输方案。由于这两个功能都在同一DD域中实现，因此我们简要讨论了基于OTF的ISAC系统的几个有希望的好处，这些好处尚未完全公布。最后，将突出显示OTF在未来无线网络中的一系列潜在应用。
The first two parts of this tutorial on orthogonal time frequency space (OTFS) modulation have discussed the fundamentals of delay-Doppler (DD) domain communications as well as some advanced technologies for transceiver design. In this letter, we will present an OTFS-based integrated sensing and communications (ISAC) system, which is regarded as an enabling technology in next generation wireless communications. In particular, we illustrate the sensing as well as the communication models for OTFS-ISAC systems. Next, we show that benefiting from time-invariant DD channels, the sensing parameters can be used for inferring the communication channels, leading to an efficient transmission scheme. As both functionalities are realized in the same DD domain, we briefly discuss several promising benefits of OTFS-based ISAC systems, which have not been completely unveiled yet. Finally, a range of potential applications of OTFS for the future wireless networks will be highlighted.
