Most of the conventional concatenated TCM employs TCM designed to maximize the minimum squared Euclidean free distance, d2free. With the matched design method, we maximize d21(t) instead of d2free, where d21(t) is the effective minimum squared Euclidean distance (MSED) when the outer code has a t-error correcting capability. The effective MSED is derived from the Euclidean/Hamming (E/H) joint weight distribution of terminated TCM. We here assume the concatenated TCM whose transmitted symbol corresponds to a symbol of outer code. The new classes of 2-dimensional (2D) and 4-dimensional (4D) codes are found by a computer search. Under the performance measures of the effective MSED or the effective multiplicity, these codes are superior to the conventional codes such as the Ungerboeck's 2D-codes when those are used as an inner code. We disclose an interesting fact that the new class of codes using rate-1/2 encoder is superior to the class of codes using rate-2/3 encoder. This fact implies that the codes using rate-1/2 encoder have two advantages: 1) better overall decoding performance and 2) less decoding complexity.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8695","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020275374","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000020275374"}],"names":[{"name":"和田山, 正"}]}]},"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_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8508","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","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":"Wadayama, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8695","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020275374","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000020275374"}]},{"creatorNames":[{"creatorName":"Wakasugi, Koichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13688","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kasahara, Masao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13689","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":"2017-01-23"}],"displaytype":"detail","filename":"E79-A_1911.pdf","filesize":[{"value":"589.3 kB"}],"format":"application/pdf","license_note":"Copyright(c)1996 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/4448/files/E79-A_1911.pdf"},"version_id":"f6c568ae-30df-47c8-9a26-62147a12ee69"}]},"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":"Matched Design Method for Concatenated Trellis-Coded Modulation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Matched Design Method for Concatenated Trellis-Coded Modulation","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-06-25"},"publish_date":"2013-06-25","publish_status":"0","recid":"4448","relation_version_is_last":true,"title":["Matched Design Method for Concatenated Trellis-Coded Modulation"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-14T04:25:31.276233+00:00"}
