Each stage of MTD-DR is formed by the traditional threshold decoder with a special shift register, called difference register (DR). After flipping each information bit, DR helps to shorten the Hamming and the Euclidian distance between a received word and the decoded codeword for hard and soft decoding, respectively. However, the MTD-DR with self-orthogonal convolutional codes (SOCCs), type 1 in this paper, makes an unavoidable error group, which depends on the tap connection patterns in the encoder, and limits the error performance. This paper introduces a class of SOCCs type 2 which can breakdown that error group, as a result, MTD-DR gives better error performance. For a shorter code (code length =4200), hard and soft decoding MTD-DR achieves 4.7dB and 6.5dB coding gain over the additive white Gaussian noise (AWGN) channel at the bit error rate (BER) 10-5, respectively. In addition, hard and soft decoding MTD-DR for a longer code (code length =80000) give 5.3dB and 7.1dB coding gain under the same condition, respectively. The hard and the soft decoding MTD-DR experiences error flooring at high Eb/N0 region. For improving overall error performance of MTD-DR, this paper proposes parity check codes concatenation with soft decoding MTD-DR as well.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"This article is approved by all authors.","subitem_description_type":"Other"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers"}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyrightⓒ2010 IEICE"}]},"item_2_rights_15":{"attribute_name":"権利（URI）","attribute_value_mlt":[{"subitem_rights":"http://www.ieice.org/jpn/trans_online/ | http://www.ieice.org/jpn/trans_online/"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1745-1337","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_19":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"540","subitem_subject_scheme":"NDC"}]},"item_2_version_type_18":{"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":"Ullah, Muhammad　Ahsan"}],"nameIdentifiers":[{"nameIdentifier":"2","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okada, Kazuma"}],"nameIdentifiers":[{"nameIdentifier":"3","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogiwara, Haruo"}],"nameIdentifiers":[{"nameIdentifier":"4","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":"2018-08-03"}],"displaytype":"detail","filename":"e93-a_11_1932.pdf","filesize":[{"value":"947.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"e93-a_11_1932.pdf","url":"https://nagaokaut.repo.nii.ac.jp/record/9/files/e93-a_11_1932.pdf"},"version_id":"3893bce1-02a5-41e9-8b99-9464b1b1ccf0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"threshold decoding","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-stage threshold decoding","subitem_subject_scheme":"Other"},{"subitem_subject":"difference register","subitem_subject_scheme":"Other"},{"subitem_subject":"error group","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":"Multi-Stage Threshold Decoding for Self-Orthogonal Convolutional Codes.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Multi-Stage Threshold Decoding for Self-Orthogonal Convolutional Codes."}]},"item_type_id":"2","owner":"2","path":["6","7","12"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-01"},"publish_date":"2012-02-01","publish_status":"0","recid":"9","relation_version_is_last":true,"title":["Multi-Stage Threshold Decoding for Self-Orthogonal Convolutional Codes."],"weko_creator_id":"2","weko_shared_id":2},"updated":"2024-02-14T06:41:30.038638+00:00"}
