| Povzetek: | 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. |
