To address this issue, we propose the Cross-Multipath Cross-Correlation (CMCC) algorithm, a joint carrier frequency offset (CFO) and time offset (TO) estimation algorithm that supports passive sensing in both non-line-of-sight (NLOS) and line-of-sight (LOS) environments. The CMCC algorithm treats the delay-Doppler spectrum of signals reflected from static objects as an environment-specific "fingerprint spectrum" that exhibits a cyclic shift property as the CFO and/or TO change. By analyzing the number of cyclic shifts, CMCC efficiently estimates both CFO and TO. Additionally, we provide a simplified version of CMCC to reduce computational complexity. Simulation results demonstrate the performance advantages of our algorithms across various configurations. date: 2024-10-07 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/SPAWC60668.2024.10694270 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2332350 doi: 10.1109/SPAWC60668.2024.10694270 lyricists_name: Masouros, Christos lyricists_id: CMASO14 actors_name: Masouros, Christos actors_id: CMASO14 actors_role: owner full_text_status: public pres_type: paper series: International Workshop on Signal Processing Advances in Wireless Communications (SPAWC) publication: IEEE Workshop on Signal Processing Advances in Wireless Communications, SPAWC volume: 2024 place_of_pub: Lucca, Italy pagerange: 316-320 event_title: 2024 IEEE 25th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC) event_dates: 10 Sep 2024 - 13 Sep 2024 issn: 1948-3252 book_title: Proceedings of IEEE Workshop on Signal Processing Advances in Wireless Communications, SPAWC citation: Wang, Xiao-Yang; Yang, Shaoshi; Chen, Mingyang; Masouros, Christos; (2024) Fingerprint-Spectrum-Based Synchronization in Asynchronous Perceptive Mobile Networks.
