The purpose of the 2D equalization is the reduction of Multiple Access Interference (MAI) which is caused by the random access and the different propagation path from each mobile station. The orthogonal coding multi-carrier CDMA multiplexes all mobile stations\u0027 data by Code Division Multiplexing (CDM). The 2D coding scheme spreads a preamble signal at time (in subchannel signals) and frequency (between subchannel signals) domains. The 2D decoding scheme estimates transmission delay time and instantaneous fading frequency from preamble signal for individual mobile stations and compensate the received data using these estimation values to reduce MAI.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "6144", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "仙石, 正和"}]}]}, "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_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©1998 IEICE"}]}, "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": "AA10826239", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168508", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Watanabe, Soichi"}], "nameIdentifiers": [{"nameIdentifier": "6140", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Takuro"}], "nameIdentifiers": [{"nameIdentifier": "6141", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sengoku, Masakazu"}], "nameIdentifiers": [{"nameIdentifier": "6142", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Abe, Takeo"}], "nameIdentifiers": [{"nameIdentifier": "6143", "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": "e81-a_6_1079.pdf", "filesize": [{"value": "801.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 801300.0, "url": {"label": "e81-a_6_1079.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1901/files/e81-a_6_1079.pdf"}, "version_id": "113705d1-7616-4e64-be50-953fc8e6b66d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "MAI", "subitem_subject_scheme": "Other"}, {"subitem_subject": "2D equalization", "subitem_subject_scheme": "Other"}, {"subitem_subject": "orthogonal coding", "subitem_subject_scheme": "Other"}, {"subitem_subject": "multi-carrier", "subitem_subject_scheme": "Other"}, {"subitem_subject": "CDMA", "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": "Two Dimensional Equalization Scheme of Orthogonal Coding Multi-Carrier CDMA", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Two Dimensional Equalization Scheme of Orthogonal Coding Multi-Carrier CDMA"}, {"subitem_title": "Two Dimensional Equalization Scheme of Orthogonal Coding Multi-Carrier CDMA", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/6527", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-07-31"}, "publish_date": "2008-07-31", "publish_status": "0", "recid": "1901", "relation": {}, "relation_version_is_last": true, "title": ["Two Dimensional Equalization Scheme of Orthogonal Coding Multi-Carrier CDMA"], "weko_shared_id": null}
