At the receiver of FCSS/DS-CDMA, the code-orthogonalizing filter (COF) produces a spreading sequence, and the receiver returns the spreading sequence to the transmitter. Then the transmitter uses the spreading sequence as its updated version. The performance of FCSS/DS-CDMA is evaluated over time-dispersive channels. The results indicate that FCSS/DS-CDMA greatly suppresses both the intersymbol interference (ISI) and multiple access interference (MAI) over time-invariant channels. FCSS/DS-CDMA is applicable to the decentralized multiple access.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_2_relation_13": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1093/ietcom/e91-b.1.53", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_44": {"attribute_name": "関係URI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "http://search.ieice.org/"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://search.ieice.org/", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_14": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright © 2008 The Institute of Electronics, Information and Communication Engineers"}]}, "item_2_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826261@@@AA11510208", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0916-8516@@@1745-1345", "subitem_source_identifier_type": "ISSN"}]}, "item_2_version_type_18": {"attribute_name": "著者版フラグ", "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": "MIYATAKE, Teruhiko"}], "nameIdentifiers": [{"nameIdentifier": "344", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "CHIBA, Kazuki"}], "nameIdentifiers": [{"nameIdentifier": "345", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HAMAMURA, Masanori"}], "nameIdentifiers": [{"nameIdentifier": "346", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TACHIKAWA, Shin\u0027ich"}], "nameIdentifiers": [{"nameIdentifier": "347", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "IEICE_E91-B_1_53.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "IEICE_E91-B_1_53.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/91/files/IEICE_E91-B_1_53.pdf"}, "version_id": "0b490366-9893-415e-b1d0-1fe0d4c614cb"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "spectrum sharing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "spread spectrum", "subitem_subject_scheme": "Other"}, {"subitem_subject": "spreading sequence", "subitem_subject_scheme": "Other"}, {"subitem_subject": "direct sequence", "subitem_subject_scheme": "Other"}, {"subitem_subject": "multipath", "subitem_subject_scheme": "Other"}, {"subitem_subject": "COF", "subitem_subject_scheme": "Other"}, {"subitem_subject": "RAKE", "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": "Asynchronous, Decentralized DS-CDMA Using Feedback-Controlled Spreading Sequences for Time-Dispersive Channels", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Asynchronous, Decentralized DS-CDMA Using Feedback-Controlled Spreading Sequences for Time-Dispersive Channels"}]}, "item_type_id": "2", "owner": "2", "path": ["5"], "permalink_uri": "http://hdl.handle.net/10173/619", "pubdate": {"attribute_name": "公開日", "attribute_value": "2011-01-26"}, "publish_date": "2011-01-26", "publish_status": "0", "recid": "91", "relation": {}, "relation_version_is_last": true, "title": ["Asynchronous, Decentralized DS-CDMA Using Feedback-Controlled Spreading Sequences for Time-Dispersive Channels"], "weko_shared_id": -1}
