However, security needs not be restricted to the upper-layer and the addition of physical-layer security also would yield a much more robust system. Therefore, in this paper, we exploit chaos communication and propose a chaos multiple-input multiple-output (MIMO) transmission scheme which achieves physical-layer security and additional channel-coding gain. A chaotic modulation symbol is multiplied to the data to be transmitted at each MIMO antenna to exploit the MIMO antenna diversity, and at the receiver, the joint MIMO detection and chaos decoding is done by maximum likelihood decoding (MLD). The conventional chaos modulation suffers from bit error rate (BER) performance degradation, while the coding gain is obtained in the proposed scheme by the chaos modulation in MIMO. We evaluate the performances of the proposed scheme by an analysis and computer simulations.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8784","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000010358963","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000010358963"}],"names":[{"name":"岡本, 英二"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers","subitem_publisher_language":"en"}]},"item_10001_relation_37":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://search.ieice.org/bin/summary.php?id=e95-b_4_1384&category=B&lang=E&year=2012&abst="}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://search.ieice.org/bin/summary.php?id=e95-b_4_1384&category=B&lang=E&year=2012&abst=","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8516","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Okamoto, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8784","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000010358963","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000010358963"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-26"}],"displaytype":"detail","filename":"e95-b_4_1384.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","license_note":"Copyright(C) 2012 IEICE http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5626/files/e95-b_4_1384.pdf"},"version_id":"502bdd92-f634-46d1-92c7-67648318c67c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"chaos coded modulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MIMO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"maximum likelihood decoding","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"convolutional code","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A chaos MIMO transmission scheme for channel coding and physical-layer security","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A chaos MIMO transmission scheme for channel coding and physical-layer security","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-07-31"},"publish_date":"2013-07-31","publish_status":"0","recid":"5626","relation_version_is_last":true,"title":["A chaos MIMO transmission scheme for channel coding and physical-layer security"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-24T00:56:51.271395+00:00"}
