20.500.12556/DiRROS-25186 Interference mitigation in one-way channel reconstruction for robust phase-based ranging Under the Integrated Sensing and Communication (ISAC) paradigm, wireless networks are evolving into multifunctional platforms that seamlessly combine data transmission with high-precision ranging for applications such as indoor navigation, asset tracking, and context-aware Internet of Things (IoT). The Multi-Carrier Phase Difference (MCPD) method has emerged as an effective technique for enabling localization in narrowband communication systems by estimating the channel frequency response (CFR) used for distance estimation. Converting the two-way CFR (TWCFR) into a one-way CFR (OWCFR) provides a physically consistent representation of the propagation channel and thus improves the ranging performance. However, existing channel reconstruction (CR) methods rely on noise-sensitive phase unwrapping which degrades in the presence of noise and interference, common in dense IoT deployments and crowded frequency bands. To address these limitations, we propose a noise-resistant OWCFR reconstruction algorithm that utilizes a peak-driven adaptive windowing strategy to generate a reference TWCFR for reliable square-root branch selection and incorporates a delay alignment correction to restore the maximum unambiguous range. Simulation and experimental results using IEEE 802.15.4 time-slotted channel hopping (TSCH) compliant devices demonstrate that the proposed method achieves robust and accurate distance estimation in more than 99.8% of interference scenarios. telecommunications channel frequency response channel impulse response document classification Bluetooth localization IEEE 802.15.4 multi-carrier phase difference one-way ranging phase-based ranging time-slotted channel hopping (TSCH) two-way ranging brezžične komunikacije radijska lokalizacija in merjenje razdalje signalna obdelava loT in senzorska omrežja ISAC-integrirano zaznavanje in komunikacija Blue tooth kanalni frekvenčni odziv kanalni impulzni odziv IEEE 802.15.4 - standard za nizkoenergijska brezžična omrežja lokalizacija fazna razlika več nosilcev enosmerno merjenje razdalje fazno merjenje razdalje časovno razdeljeno preskakovanje kanalov (TSCH) dvosmerno merjenje razdalje true false true IEEE ZDA Angleški jezik Slovenski jezik © 2025 The Authors.
