Özet
Integrated sensing and communication (ISAC) has attracted significant attention in recent years, driven by the growing demand for spectrum efficiency and the additional opportunities arising from leveraging communication signals for sensing. Among applications of ISAC, localization in cellular networks stands out as particularly important and is projected to become even more critical as cellular deployments become increasingly dense. This paper proposes a cellular localization method based on distributed ISAC that leverages physical random access channel (PRACH) preambles to estimate the positions of multiple targets, such as uncrewed aerial vehicles (UAVs), using direction of arrival (DoA) estimation. The simulation and laboratory measurement experiments demonstrate promising localization results of the distributed ISAC approach. Furthermore, the Cramér-Rao lower bound (CRLB) on localization error is derived as a theoretical benchmark for evaluating the estimation accuracy of the proposed method across different cell geometries.
