The PC/SS systems can provide the high-speed data transmission capability by transmitting multiple pseudo-noise sequences out of a pre-assigned sequence set. The performance is evaluated in terms of average bit error rate (BER) by numerical computation. In nonfading white gaussian channel, the PC/SS systems are superior to conventional direct sequence spread spectrum (DS/SS) systems under the identical spreading factor condition. In Rayleigh fading channel, the performance of the PC/SS system without diversity is poorer than that of the DS/SS system. By including the explicit and implicit diversity, the performance of the PC/SS system becomes better than that of conventional DS/SS systems. A longer spreading sequence is assignable to a PC/SS system having the spreading factor equal to that in the conventional DS/SS system. Hence, the error control coding is easily. It is found that the PC/SS systems including diversity and Reed-Solomon coding improves the multiple access performance.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"5799","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐々木, 重信"}]},{"nameIdentifiers":[{"nameIdentifier":"5800","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©1995 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":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168516","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sasaki, Shigenobu"}],"nameIdentifiers":[{"nameIdentifier":"5795","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Hisakazu"}],"nameIdentifiers":[{"nameIdentifier":"5796","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhu, Jinkang"}],"nameIdentifiers":[{"nameIdentifier":"5797","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Marubayashi, Gen"}],"nameIdentifiers":[{"nameIdentifier":"5798","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_0024.pdf","filesize":[{"value":"833.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1_0024.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1834/files/1_0024.pdf"},"version_id":"af59b93b-bb36-40a0-8dcf-604328c03336"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"communication theory","subitem_subject_scheme":"Other"},{"subitem_subject":"radio communication","subitem_subject_scheme":"Other"},{"subitem_subject":"code division multiple access","subitem_subject_scheme":"Other"},{"subitem_subject":"Rayleigh fading","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":"Multiple access performance of parallel combinatory spread spectrum communication systems in nonfading and Rayleigh fading channels","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Multiple access performance of parallel combinatory spread spectrum communication systems in nonfading and Rayleigh fading channels"},{"subitem_title":"Multiple access performance of parallel combinatory spread spectrum communication systems in nonfading and Rayleigh fading channels","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":"1834","relation_version_is_last":true,"title":["Multiple access performance of parallel combinatory spread spectrum communication systems in nonfading and Rayleigh fading channels"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:41.300685+00:00"}
