This condition could mislead the effective algorithm in finding the echo path replica. In this paper, we have defined a new algorithm for tap adaptations in the echo canceler based on correlation function (CLMS), where the near-end signal is existing. In this approach, the gradient search algorithm is obtained from the correlation function of the input signal. That is, the tap adaptation process is performed in a newly defined correlation path, and then copied into the echo path replica digital filter The computer simulation shows the robustness of the proposed algorithm in the presence of double-talk signal.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学工学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/1486"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0389-102X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025048X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学工学部紀要"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "1999-03", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "57", "bibliographicPageEnd": "142", "bibliographicPageStart": "137"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "No57p137.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2001634/files/No57p137.pdf"}, "version_id": "c49751f2-0af5-4159-956f-270c08fefdd3"}]}, "item_title": "double-talk状態でのエコーキャンセリングを行なう相関LMSアルゴリズムの提案", "item_type_id": "15", "owner": "1", "path": ["1642837875288", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/1486", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-08-23"}, "publish_date": "2007-08-23", "publish_status": "0", "recid": "2001634", "relation": {}, "relation_version_is_last": true, "title": ["double-talk状態でのエコーキャンセリングを行なう相関LMSアルゴリズムの提案"], "weko_shared_id": -1}
