In a short-range MIMO transmission, an optimal element spacing that maximizes the channel capacity exists for a given transmit distance between the transmitter and receiver. We focus on the fact that the weight matrix by zero forcing (ZF) at the optimal element spacing can be obtained by using dividers and 90-degree phase shifters because it can be expressed by a unitary matrix. The channel capacity by the proposed method is next derived for the evaluation of the exact limitation of the channel capacity. Moreover, it is shown that an optimal weight when using directional antennas can be expressed by using only dividers, 90-degree phase shifters, and attenuators, regardless of the beam width of the directional antenna. Finally, bit error rate and channel capacity evaluations by both simulation and measurement confirm the effectiveness of the proposed method.", "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.E97.B.620", "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)2014 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": "Kataoka, Ryochi"}], "nameIdentifiers": [{"nameIdentifier": "5484", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimori, Kentaro"}], "nameIdentifiers": [{"nameIdentifier": "5485", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraguri, Takefumi"}], "nameIdentifiers": [{"nameIdentifier": "5486", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Honma, Naoki"}], "nameIdentifiers": [{"nameIdentifier": "5487", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Seki, Tomohiro"}], "nameIdentifiers": [{"nameIdentifier": "5488", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraga, Ken"}], "nameIdentifiers": [{"nameIdentifier": "5489", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Makino, Hideo"}], "nameIdentifiers": [{"nameIdentifier": "5490", "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": "E97-B_3_620-630.pdf", "filesize": [{"value": "2.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2500000.0, "url": {"label": "E97-B_3_620-630.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1765/files/E97-B_3_620-630.pdf"}, "version_id": "61bbdda3-311f-4652-9dda-47402a444bd9"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "short-range MIMO transmission", "subitem_subject_scheme": "Other"}, {"subitem_subject": "zero forcing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "unitary matrix", "subitem_subject_scheme": "Other"}, {"subitem_subject": "90-degree phase shifter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "optimal element spacing", "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": "Analog Decoding Method for Simplified Short-Range MIMO Transmission", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Analog Decoding Method for Simplified Short-Range MIMO Transmission"}, {"subitem_title": "Analog Decoding Method for Simplified Short-Range MIMO Transmission", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/30686", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-02"}, "publish_date": "2014-12-02", "publish_status": "0", "recid": "1765", "relation": {}, "relation_version_is_last": true, "title": ["Analog Decoding Method for Simplified Short-Range MIMO Transmission"], "weko_shared_id": null}
