Feed-Forward (FF-) and FeedBack (FB-) structures have been proposed for Blind Source Separation (BSS). The FF-BSS systems have some degree of freedom in the solution space, and signal distortion is likely to occur in convolutive mixtures. On the other hand, FB-BSS structure is hard to cause signal distortion. However, the FB-BSS system requires a condition for the transmission delay time in the mixing process. The FF-BSS systems and the FB-BSS system are compared based on the transmission time delay in the mixing process. Even though the FB-BSS can provide good separation performance, there exit some limitations on location of the signal sources and the sensors.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域　電子情報学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEICE The Institute of Electronics, Information and Communication Engineers"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110006204637/","subitem_relation_type_select":"URI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11943613","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0913-5685","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"堀田, 明秀"},{"creatorName":"ナカヤマ, ケンジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中山, 謙二"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"平野, 晃宏"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-NAKAYAMA-K-1_m.pdf","filesize":[{"value":"204.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-NAKAYAMA-K-1_m.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9657/files/TE-PR-NAKAYAMA-K-1_m.pdf"},"version_id":"ca7d5710-5e38-40e3-a87e-10c814df4ada"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"畳み込み混合過程の伝達遅延に基づくBSSの信号源分離性能解析(ブロードバンド無線アクセス技術,無線信号処理,無線通信,一般)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"畳み込み混合過程の伝達遅延に基づくBSSの信号源分離性能解析(ブロードバンド無線アクセス技術,無線信号処理,無線通信,一般)"},{"subitem_title":"An analysis of source separation performances in BSS based on transmission delays in convolutive mixture","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"9657","relation_version_is_last":true,"title":["畳み込み混合過程の伝達遅延に基づくBSSの信号源分離性能解析(ブロードバンド無線アクセス技術,無線信号処理,無線通信,一般)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:51:33.691628+00:00"}
