On the other hand amplitude modulation and coherent detection are employed in a high-speed data communication system for the purpose of using a frequency band efficiently. This paper describes the effects of the reference carrier phase error on the high-speed data communication system employing the Viterbi detector, First the relation between the phase error and the effective signal-to-noise ratio (an evaluation function of the system) is derived. Secondly further analysis is performed regarding a SSB-AM (single-sideband amplitude modulation) system. Numerical results indicate that the performance of the data communication system is degraded substantially due to the reference carrier phase errorr. And it was also shown that the allowable phase error in a SSB-AM system with data rates of 12,000 bits/s is about 2 degrees.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"167878","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ogawa, Yasutaka"}]},{"nameIdentifiers":[{"nameIdentifier":"167879","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sengoku, Masakazu"}]},{"nameIdentifiers":[{"nameIdentifier":"167880","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsumoto, Tadashi"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道大学"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00230223","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385602X","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小川, 恭孝"}],"nameIdentifiers":[{"nameIdentifier":"167875","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仙石, 正和"}],"nameIdentifiers":[{"nameIdentifier":"167876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 正"}],"nameIdentifiers":[{"nameIdentifier":"167877","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":"2019-08-21"}],"displaytype":"detail","filename":"S89_87-98.pdf","filesize":[{"value":"761.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S89_87-98.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/30240/files/S89_87-98.pdf"},"version_id":"aa8303ff-19d6-4231-980b-18a0af15cdb7"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ビタビ識別器を用いた高速デ-タ通信系に対する規準搬送波位相誤差の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ビタビ識別器を用いた高速デ-タ通信系に対する規準搬送波位相誤差の影響"},{"subitem_title":"ビタビ識別器を用いた高速デ-タ通信系に対する規準搬送波位相誤差の影響","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1290"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-17"},"publish_date":"2013-05-17","publish_status":"0","recid":"30240","relation_version_is_last":true,"title":["ビタビ識別器を用いた高速デ-タ通信系に対する規準搬送波位相誤差の影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:00:48.593387+00:00"}
