Although the opposed transceiving antennas are assumed to be accurately positioned in previous studies regarding SR-MIMO, a very important issue is to evaluate the performance degradation due to displacement between MIMO transceivers. In SR-MIMO over the millimeter-wave band, any displacement is perceived as significant because the wavelength is small. This paper evaluates the influence on SR-MIMO transmission performance over millimeter-wave caused by displacement between the transmitting and receiving antennas. The channel capacity is found to degrade by 5% when the horizontal displacement is 1mm and by 2.7% when the rotational displacement is 10 degrees. In addition, comparing performances obtained with a number of antenna array arrangements clarifies that a square pattern arrangement is suitable for short-range wireless transmission.", "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/transcom.E94.B.2891", "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": "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)2011 IEICE"}, {"subitem_rights": "本文データは学協会の許諾に基づきEJサイト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_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826261", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168516", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hiraga, Ken"}], "nameIdentifiers": [{"nameIdentifier": "5563", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Seki, Tomohiro"}], "nameIdentifiers": [{"nameIdentifier": "5564", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimori, Kentaro"}], "nameIdentifiers": [{"nameIdentifier": "5565", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishikawa, Kenjiro"}], "nameIdentifiers": [{"nameIdentifier": "5566", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Toyoda, Ichihiko"}], "nameIdentifiers": [{"nameIdentifier": "5567", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Uehara, Kazuhiro"}], "nameIdentifiers": [{"nameIdentifier": "5568", "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": "E94-B_10_2891-2895.pdf", "filesize": [{"value": "684.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 684200.0, "url": {"label": "E94-B_10_2891-2895.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1783/files/E94-B_10_2891-2895.pdf"}, "version_id": "410fc2bc-1037-4c95-a0f6-b3b75870b554"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "short-range", "subitem_subject_scheme": "Other"}, {"subitem_subject": "MIMO", "subitem_subject_scheme": "Other"}, {"subitem_subject": "millimeter-wave", "subitem_subject_scheme": "Other"}, {"subitem_subject": "antennas", "subitem_subject_scheme": "Other"}, {"subitem_subject": "parallel transmission", "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": "Analyses of Antenna Displacement in Short-Range MIMO Transmission over Millimeter-Wave", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Analyses of Antenna Displacement in Short-Range MIMO Transmission over Millimeter-Wave"}, {"subitem_title": "Analyses of Antenna Displacement in Short-Range MIMO Transmission over Millimeter-Wave", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/30677", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-02"}, "publish_date": "2014-12-02", "publish_status": "0", "recid": "1783", "relation": {}, "relation_version_is_last": true, "title": ["Analyses of Antenna Displacement in Short-Range MIMO Transmission over Millimeter-Wave"], "weko_shared_id": null}
