The bandlimited condition is satisfied by using an ideal bandlimited signal as an excited signal. A waveform synthesis digital filter is used to extrapolate fractionally observed data, using the bandlimited excited signal. Therefore, the proposed method reduces the extrapolation problem to a digital filter estimation problem. Digital filter coefficients are obtained by solving linear equations, which are formulated to minimize the mean-square error between a part of the extrapolated signal and the fractionally observed data. The modified Gram-Schmidt (MGS) procedure is applied to finding the least-square solution of the filter coefficients, due to its superior numerical stability. The recursive version of the MGS procedure is suited to real-time hardware implementation. The proposed algorithm is shown to have good performance in extrapolating the fractional data, observed in a single as well as multiple time windows. This concept is applicable not only to the signal extrapolation but also to the spectral estimation.","subitem_description_type":"Abstract"}]},"item_8_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE / Ohmsha Ltd"}]},"item_8_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":"Chen, Y."}],"nameIdentifiers":[{"nameIdentifier":"10989","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakayama, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"353","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00207945","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00207945"},{"nameIdentifier":"00207945","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000000207945"}]}]},"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-234.pdf","filesize":[{"value":"523.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-NAKAYAMA-K-234.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/7975/files/TE-PR-NAKAYAMA-K-234.pdf"},"version_id":"79828ed2-526d-4759-8e8f-997a54da2b56"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"A band-limited signal extrapolation algorithm using waveform synthesis digital filter","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A band-limited signal extrapolation algorithm using waveform synthesis digital filter"}]},"item_type_id":"8","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"7975","relation_version_is_last":true,"title":["A band-limited signal extrapolation algorithm using waveform synthesis digital filter"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-06-20T06:37:10.043464+00:00"}
