The PC/SS systems are multicode SS systems based on orthogonal pseudo-noise (PN) sequences. Data is transmitted by delivering a combination of multiple PN sequences among a set of pre-assigned PN sequences. In the MPC/SS systems, every PN sequence on transmission is modulated by q-ary coherent or differential phase shift keying (PSK). Symbol error rate (SER) and average bit error rate (BER) in coherent and differential MPC/SS systems are investigated. The BER comparison between the MPC/SS systems and simple multicode SS systems with q-ary coherent and differential PSK is also presented. Numerical results show that the MPC/SS systems are superior to the conventional q-ary PSK systems, if they have equal spectral efficiency.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6161","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐々木, 重信"}]},{"nameIdentifiers":[{"nameIdentifier":"6162","nameIdentifierScheme":"WEKO"}],"names":[{"name":"菊池, 久和"}]}]},"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©1997 IEICE（許諾番号07RB0183）"}]},"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":"Sasaki, Shigenobu"}],"nameIdentifiers":[{"nameIdentifier":"6157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Hisakazu"}],"nameIdentifiers":[{"nameIdentifier":"6158","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhu, Jinkang"}],"nameIdentifiers":[{"nameIdentifier":"6159","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Marubayashi, Gen"}],"nameIdentifiers":[{"nameIdentifier":"6160","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","filename":"1_0023.pdf","filesize":[{"value":"627.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1_0023.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1905/files/1_0023.pdf"},"version_id":"98f3d948-fcf1-4b56-8422-effebd03072c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"spread spectrum","subitem_subject_scheme":"Other"},{"subitem_subject":"multicode systems","subitem_subject_scheme":"Other"},{"subitem_subject":"multiphase modulation","subitem_subject_scheme":"Other"},{"subitem_subject":"symbol error rate","subitem_subject_scheme":"Other"},{"subitem_subject":"bit error rate","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":"Error rate analysis of coherent and differential multiphase parallel combinatorial spread spectrum communication systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Error rate analysis of coherent and differential multiphase parallel combinatorial spread spectrum communication systems"},{"subitem_title":"Error rate analysis of coherent and differential multiphase parallel combinatorial spread spectrum communication systems","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"1905","relation_version_is_last":true,"title":["Error rate analysis of coherent and differential multiphase parallel combinatorial spread spectrum communication systems"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:45.546033+00:00"}
