Thus orthogonal sequence as spreading sequence would achieve ideal throughput if each of packets accomplish perfect synchronization. In the presence of any ambiguity in synchronizations, however, quasi-synchronous(QS)sequences suit well with CDMA S-ALOHA system. In this paper, we introduce new QS-sequences obtained from the orthogonal Gold sequences and discuss their performance when applying to CDMA S-ALOHA systems. As a result, withstanding to access timing error, good performance is ensured with this sequence under the environment of AWGN, MAI(multiple access interference )and frequency non-selective fading, that is, micro or pico cellular systems and indoor wireless LANs.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/7207"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEICE","subitem_publisher_language":"en"}]},"item_10_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://search.ieice.org/bin/summary.php?id=e81-a_11_2274&category=A&year=1998&lang=E&abst=&auth=1","subitem_relation_type_select":"URI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 1998 IEICE  許諾番号　06RB0162号","subitem_rights_language":"ja"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8508","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Saito, Masato","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14702","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamazato, Takaya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14703","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katayama, Masaaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14704","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawa, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14705","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":"2018-02-19"}],"displaytype":"detail","filename":"E81-A-2274.pdf","filesize":[{"value":"761.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"E81-A-2274.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/5601/files/E81-A-2274.pdf"},"version_id":"b8797c51-91ae-4307-bab7-9774cf52f5cf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CDMA slotted ALOHA system","subitem_subject_scheme":"Other"},{"subitem_subject":"QS-sequences","subitem_subject_scheme":"Other"},{"subitem_subject":"access timing error","subitem_subject_scheme":"Other"},{"subitem_subject":"orthogonal Gold sequences","subitem_subject_scheme":"Other"},{"subitem_subject":"flat fading channel","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":"New Quasi-Synchronous Sequences for CDMA Slotted ALOHA Systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New Quasi-Synchronous Sequences for CDMA Slotted ALOHA Systems","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2006-12-20"},"publish_date":"2006-12-20","publish_status":"0","recid":"5601","relation_version_is_last":true,"title":["New Quasi-Synchronous Sequences for CDMA Slotted ALOHA Systems"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:29:41.469161+00:00"}
