As the arrays grow in size, the conventional far-field assumption is increasingly being violated and curvature of the wavefront should be taken into account. We explicitly contrast near-field and far-field uplink localization performance from a Fisher information perspective and show how a simple algorithm can provide a rough initial estimate for maximum likelihood estimation. Our results show that invoking the more general near-field model allows for joint estimation of a user's location and clock bias in the uplink, while the far-field model may lead to overly pessimistic performance assessment.","url_abs":"https://arxiv.org/abs/1907.07411v1","url_pdf":"https://arxiv.org/pdf/1907.07411v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"near-field-joint-localization-and","repo_url":"https://github.com/henkwymeersch/NearField5GLocalization","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
