In a CDMA Unslotted ALOHA system, Multiple Access Interference(MAI)may bring about errors in PR/CA. The MAI mainly stems from already recognized packets and newly arriving packets under the execution of PR/CA. This characteristic  of asynchronous transmission in CDMA U-ALOHA systems implies that only one or a few packets arrive at the receiver within a short interval of a execution. Furthermore, newly arriving packets are recognized and code-acquired by using a short preamble part. Consequently, the MAI from the packets under the execution of the PR/CA will be small.Focusing on that point, this paper proposes applying the IC scheme in order to suppress the MAI from the already recognized and code-acquired packets.A performance evaluation demonstrates that such an application is valid due to the small amount of MAI from the packets under the execution of PR/CA. In addition,we demonstrates that the scheme reduces false recognition rather than mis-recognition. Such a scheme improves the performance of not only PR/CA, but also the throughput.", "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/2237/7224"}]}, "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=e88-a_6_1605\u0026category=A\u0026year=2005\u0026lang=E\u0026abst=\u0026auth=1", "subitem_relation_type_select": "URI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright 2005 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": "Tadokoro, Yukihiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "14768", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Okada, Hiraku", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "14769", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamazato, Takaya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "14770", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Katayama, Masaaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "14771", "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", "download_preview_message": "", "file_order": 0, "filename": "E88-A-1605.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "E88-A-1605.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/5618/files/E88-A-1605.pdf"}, "version_id": "37096c03-7516-4529-8d8f-d9506822e709"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "CDMA Unslotted ALOHA", "subitem_subject_scheme": "Other"}, {"subitem_subject": "successive interference cancellation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "throughput", "subitem_subject_scheme": "Other"}, {"subitem_subject": "packet recognition", "subitem_subject_scheme": "Other"}, {"subitem_subject": "code acquisition", "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": "Application of Successive Interference Cancellation to a Packet-Recognition/Code-Acquisition Scheme in CDMA Unslotted ALOHA Systems", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Application of Successive Interference Cancellation to a Packet-Recognition/Code-Acquisition Scheme in CDMA Unslotted ALOHA Systems", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/7224", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2006-12-25"}, "publish_date": "2006-12-25", "publish_status": "0", "recid": "5618", "relation": {}, "relation_version_is_last": true, "title": ["Application of Successive Interference Cancellation to a Packet-Recognition/Code-Acquisition Scheme in CDMA Unslotted ALOHA Systems"], "weko_shared_id": -1}
