The DSDTS is devised to enable a small scale earth station to acquire a limited portion of data in the deep space exploration. The PSK/FSK DSDTS is an example of the proposed DSDTS. In this system, energy of some bit-intervals of PSK channel which is assigned to high speed channel is utilized to one bit energy of FSK channel which is assigned to a low speed channel for a small earth station. In this paper, nearly optimum signal detection schemes basing upon the Maximum A Posteriori Probability (MAP) method are constructed for PSK/FSK DSDTS. The formulations of bit error probability for each channel according to these dectectors are also introduced.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125762000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"日本電信電話公社"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"堀川, 真吾"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浅野, 正一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 紘二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野村, 民也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HORIKAWA, Shingo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ASANO, Shoichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITOH, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOMURA, Tamiya","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0125762.pdf","filesize":[{"value":"689.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125762.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32484/files/SA0125762.pdf"},"version_id":"3b7341d5-5ef4-4841-a032-caf3ee2510a6"}]},"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":"<論文>深宇宙探索における複速度通信方式","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>深宇宙探索における複速度通信方式"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32484","relation_version_is_last":true,"title":["<論文>深宇宙探索における複速度通信方式"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:31:10.119751+00:00"}
