To provide advanced applications and services by the sensor networks, data collection including node location is essential. Hence the location estimation is important and many localization schemes have been proposed. Time of arrival (TOA) localization is one of the popular schemes because of its high estimation accuracy in ultra wide-band (UWB) sensor networks. However, a non-line-of-sight (NLOS) environment between the target and the anchor nodes causes a serious estimation error because the time is delayed more than its true one. Thus, the NLOS nodes should be detected and eliminated for estimation. As a well-known NLOS detection scheme, an iterative minimum residual (IMR) scheme which has low calculation complexity is used for detection. However, the detection error exists in IMR scheme due to the measurement error. Therefore, in this paper, we propose a new IMR-based NLOS detection scheme and show its performance improvement by computer simulations.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"9132","nameIdentifierScheme":"WEKO"}],"names":[{"name":"福田, 一隆"}]},{"nameIdentifiers":[{"nameIdentifier":"8784","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000010358963","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000010358963"}],"names":[{"name":"岡本, 英二"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers","subitem_publisher_language":"en"}]},"item_10001_relation_37":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://search.ieice.org/bin/summary.php?id=e95-a_10_1658&category=A&lang=E&year=2012&abst="}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://search.ieice.org/bin/summary.php?id=e95-a_10_1658&category=A&lang=E&year=2012&abst=","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8508","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fukuda, Kazutaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9132","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okamoto, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8784","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000010358963","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000010358963"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-27"}],"displaytype":"detail","filename":"e95-a_10_1658.pdf","filesize":[{"value":"4.3 MB"}],"format":"application/pdf","license_note":"Copyright(C) 2012 IEICE http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5714/files/e95-a_10_1658.pdf"},"version_id":"50c80700-a15e-4506-88cf-ee4d452e4cc6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sensor networks","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"UWB","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TOA-based position estimation system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"NLOS environment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"IMR method","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Performance Improvement of IMR-Based NLOS Detection in Indoor Ultra Wide-Band TOA Localization","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance Improvement of IMR-Based NLOS Detection in Indoor Ultra Wide-Band TOA Localization","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-07-31"},"publish_date":"2013-07-31","publish_status":"0","recid":"5714","relation_version_is_last":true,"title":["Performance Improvement of IMR-Based NLOS Detection in Indoor Ultra Wide-Band TOA Localization"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-24T02:52:37.056602+00:00"}
