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'ich"}],"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","filename":"IEICE_E91-B_1_53.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-01-26"},"publish_date":"2011-01-26","publish_status":"0","recid":"91","relation_version_is_last":true,"title":["Asynchronous, Decentralized DS-CDMA Using Feedback-Controlled Spreading Sequences for Time-Dispersive Channels"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T13:45:05.729167+00:00"}
