In this letter, the detection performance using eigenvectors, which are obtained by singular value decomposition for MIMO channel matrix, is evaluated in actual indoor propagation environment. Moreover, a new diversity method using multiple eigenvectors is proposed to enhance the performance of the intruder detection using eigenvectors. Scenarios that are effective for 1st and 2nd eigenvectors is verified and the effectiveness using multiple eigenvectors is shown compared to the MIMO sensor using the channel matrix.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1587/comex.3.61 ", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://www.jstage.jst.go.jp/", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright(C)2014 IEICE"}, {"subitem_rights": "本文データは学協会の許諾に基づきJ-Stageから複製したものである"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "21870136", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ushiki, Keita"}], "nameIdentifiers": [{"nameIdentifier": "5401", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimori, Kentaro"}], "nameIdentifiers": [{"nameIdentifier": "5402", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Honma, Naoki"}], "nameIdentifiers": [{"nameIdentifier": "5403", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Makino, Hideo"}], "nameIdentifiers": [{"nameIdentifier": "5404", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "3_2_61-67.pdf", "filesize": [{"value": "463.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 463000.0, "url": {"label": "3_2_61-67.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1748/files/3_2_61-67.pdf"}, "version_id": "5d702ca7-49a1-4c59-8ced-8b4adfb079d6"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "MIMO sensor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "propagation channel", "subitem_subject_scheme": "Other"}, {"subitem_subject": "eigenvector", "subitem_subject_scheme": "Other"}, {"subitem_subject": "indoor propagation environment", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Experimental evaluation on MIMO sensor employing eigenvector diversity", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Experimental evaluation on MIMO sensor employing eigenvector diversity"}, {"subitem_title": "Experimental evaluation on MIMO sensor employing eigenvector diversity", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/30670", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-02"}, "publish_date": "2014-12-02", "publish_status": "0", "recid": "1748", "relation": {}, "relation_version_is_last": true, "title": ["Experimental evaluation on MIMO sensor employing eigenvector diversity"], "weko_shared_id": null}
