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", "download_preview_message": "", "file_order": 0, "filename": "1_0024.pdf", "filesize": [{"value": "833.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 833300.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/6218", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "1834", "relation": {}, "relation_version_is_last": true, "title": ["Multiple access performance of parallel combinatory spread spectrum communication systems in nonfading and Rayleigh fading channels"], "weko_shared_id": null}
