The proposed method is based on a modified adaptive Butler-Cantoni equalizer that decouples noise variance estimation from channel estimation. The bias in time delay estimates that is induced by input noise is reduced by an IIR whitening filter whose coefficients are found by the Burg algorithm. For step time-variant delays, a dual mode operation scheme is adopted in which we define a normal operating (tracking) mode and an interrupt operating (optimization) mode. In the tracking mode, only a few coefficients of the impulse response vector are monitored through L_1-normed finite forward differences tracking, while in the optimization mode, the time delay optimized. Simulation results confirm the superiority of the proposed approach at low signal-to-noise ratios.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"copyright(c)2005 IEICE\n許諾番号：07RB0174　\nhttp://www.ieice.org/jpn/trans_online/index.html","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人電子情報通信学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"GAMBA, Jonah"},{"subitem_text_value":"SHIMAMURA, Tetsuya"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003094"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学工学部情報工学科"},{"subitem_text_value":"埼玉大学大学院理工学研究科数理電子情報部門情報システム工学領域"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Information and Computer Sciences, Saitama University"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2005-4"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"GAMBA, Jonah"},{"creatorName":"ガンバ, ヨナー","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島村, 徹也"},{"creatorName":"シマムラ, テツヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003094.pdf","filesize":[{"value":"508.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003094.pdf","url":"https://sucra.repo.nii.ac.jp/record/12901/files/A1003094.pdf"},"version_id":"b0673b7b-bab7-426e-898e-a2d99ad2b860"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"time delay estimation","subitem_subject_scheme":"Other"},{"subitem_subject":"adaptive Butler-Cantoni equalizer","subitem_subject_scheme":"Other"},{"subitem_subject":"delay optimization","subitem_subject_scheme":"Other"},{"subitem_subject":"L_1-norm","subitem_subject_scheme":"Other"},{"subitem_subject":"finite difference","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Equalizer-Aided Time Delay Tracking Based on L_1-Normed Finite Differences(Digital Signal Processing)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Equalizer-Aided Time Delay Tracking Based on L_1-Normed Finite Differences(Digital Signal Processing)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-04"},"publish_date":"2007-10-04","publish_status":"0","recid":"12901","relation_version_is_last":true,"title":["Equalizer-Aided Time Delay Tracking Based on L_1-Normed Finite Differences(Digital Signal Processing)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:46:35.956532+00:00"}
