For MAAC, we propose a coding scheme of (k + 1)-ary error-correcting signature codes. We give binary and non-binary signature codes. They are the best error-correcting signature codes for MAAC, in the sense that they have highest sum rates known. For TWRC, we propose a low-complexity two-user turbo decoding scheme when turbo codes are applied in two users. The approximate decoding algorithm preserves low decoding complexity over the Gaussian TWRC, without much performance degradation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_description_18":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_dissertation_number_28":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第657号"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/di.2017.0000016167","subitem_identifier_reg_type":"JaLC"}]},"item_3_relation_16":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"BB1675433X","subitem_relation_type_select":"NCID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"掲載刊行物所蔵情報へのリンク ／ Link to Contents"}],"subitem_relation_type":"isFormatOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doors.doshisha.ac.jp/opac/opac_link/bibid/BB12863897/?lang=0","subitem_relation_type_select":"URI"}}]},"item_3_text_8":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"理工学研究科"}]},"item_3_text_9":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Graduate School of Science and Engineering"}]},"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":"路, 姍","creatorNameLang":"ja"},{"creatorName":"ロ, サン","creatorNameLang":"ja-Kana"},{"creatorName":"Lu, Shan","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-07-04"}],"displaytype":"detail","filename":"k657.pdf","filesize":[{"value":"460.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨/abstaract","objectType":"abstract","url":"https://doshisha.repo.nii.ac.jp/record/1148/files/k657.pdf"},"version_id":"9b0704c7-fded-4929-8d66-bb5dd0056101"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-11-26"}],"displaytype":"detail","filename":"zk657.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"zk657.pdf","objectType":"fulltext","url":"https://doshisha.repo.nii.ac.jp/record/1148/files/zk657.pdf"},"version_id":"439a776c-47de-4ad7-bb5f-d70311aec92b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"多端子通信システム","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Signature 符号","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"多重接続通信路","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ターボ符号","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"双方向中継通信路","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Multiuser Communication System","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Signature Code","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Multiple Access Adder Channel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Turbo Code","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Two-Way Relay Channel","subitem_subject_language":"en","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Coding and decoding for multiuser communication systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Coding and decoding for multiuser communication systems","subitem_title_language":"en"}]},"item_type_id":"3","owner":"20","path":["4188","7207"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-07-04"},"publish_date":"2014-07-04","publish_status":"0","recid":"1148","relation_version_is_last":true,"title":["Coding and decoding for multiuser communication systems"],"weko_creator_id":"20","weko_shared_id":-1},"updated":"2023-12-20T07:19:36.825495+00:00"}
