摘要:

一体化感知与通信(ISAC)被视为未来移动网络的关键组成部分,在学术界和工业界均受到广泛关注。与射频(RF)ISAC的兴起类似,自由空间光通信与光感知的融合催生了光ISAC(O-ISAC),它被认为是射频ISAC的有力补充。本文首先介绍了O-ISAC的通用系统结构,随后详细阐述了O-ISAC的三大优势,即提升通信速率、增强感知精度以及降低干扰。接着,本文基于脉冲波形、恒模波形和多载波波形,讨论了O-ISAC的波形设计与资源分配问题。此外,本文还提出了O-ISAC的未来发展趋势与挑战,以期为后续研究提供有价值的方向。

英文摘要:

Integrated sensing and communication (ISAC) is viewed as a crucial component of future mobile networks and has gained much interest in both academia and industry. Similar to the emergence of radio-frequency (RF) ISAC, the integration of free space optical communication and optical sensing yields optical ISAC (O-ISAC), which is regarded as a powerful complement to its RF counterpart. In this article, we first introduce the generalized system structure of O-ISAC, and then elaborate on three advantages of O-ISAC, i.e., increasing communication rate, enhancing sensing precision, and reducing interference. Next, waveform design and resource allocation of O-ISAC are discussed based on pulsed waveform, constant-modulus waveform, and multi-carrier waveform. Furthermore, we put forward future trends and challenges of O-ISAC, which are expected to provide some valuable directions for future research.
