In this paper, coded modulation schemes using product codes composed of integer codes over hexagonal constellations are proposed. The peak-to-average power ratio of an isotropy 19-Hexagonal constellation is 0.56 dB lower than that of 16QAM. In addition, integer codes can define its correctable error in the vicinity of signal points. Therefore, it is suitable for the practical communication channel. Our coded modulation simulation results over 19, 37 and 61 hexagonal constellations showed lower bit error rate than the results on square QAM constellations.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.14923/transcomj.2019JBP3024","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://search.ieice.org/index.html","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2020 IEICE"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18810209","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"北原, 裕久","creatorNameLang":"ja"},{"creatorName":"キタハラ, ヒロヒサ","creatorNameLang":"ja-Kana"},{"creatorName":"KITAHARA, Hirohisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森田, 啓義","creatorNameLang":"ja"},{"creatorName":"モリタ, ヒロヨシ","creatorNameLang":"ja-Kana"},{"creatorName":"MORITA, Hiroyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"眞田, 亜紀子","creatorNameLang":"ja"},{"creatorName":"マナダ, アキコ","creatorNameLang":"ja-Kana"},{"creatorName":"MANADA, Akiko","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":"2020-11-19"}],"displaytype":"detail","filename":"j103-b_5_184.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"j103-b_5_184","url":"https://uec.repo.nii.ac.jp/record/9680/files/j103-b_5_184.pdf"},"version_id":"6265a793-a58c-47d1-85fb-814ab753a998"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"整数符号","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"積符号","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"PAPR","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"六角形格子","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"integer codes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"product codes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PAPR","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hexagonal constellations","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"六角形格子上の積符号を用いた符号化変調方式によるPAPRの低減","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"六角形格子上の積符号を用いた符号化変調方式によるPAPRの低減","subitem_title_language":"ja"},{"subitem_title":"PAPR Reduction of Coded Modulation Schemes Using Product Codes over Hexagonal Constellations","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-11-19"},"publish_date":"2020-11-19","publish_status":"0","recid":"9680","relation_version_is_last":true,"title":["六角形格子上の積符号を用いた符号化変調方式によるPAPRの低減"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-03-07T01:50:00.623835+00:00"}
