For complicated multipath propagation environment, it is not enough to estimate only the delay-times of the signals. Some other information should be required to identify the signal path. The proposed method can estimate the frequency characteristic of each signal in addition to its delay-time. One method called modified (Root) MUSIC algorithm is known as a technique that can treat both of the parameters (frequency characteristic and delay-time). However, the method is based on some approximations in the signal decorrelation, that sometimes make problems. Therefore, further modification should be needed to apply the method to the complicated scattering analysis. In this paper, we propose to apply a time-domain null filtering scheme to reduce some of the dominant signal components. It Can be shown by a simple experiment that the new technique can enhance the estimation accuracy of the frequency characteristic in the Root-MUSIC algorithm.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright(C)1996 IEICE"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826261", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168516", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yamada, Hiroyoshi"}], "nameIdentifiers": [{"nameIdentifier": "50", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaguchi, Yoshio"}], "nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sengoku, Masakazu"}], "nameIdentifiers": [{"nameIdentifier": "5791", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110003217602.pdf", "filesize": [{"value": "664.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 664500.0, "url": {"label": "110003217602.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1832/files/110003217602.pdf"}, "version_id": "dfafa754-710d-4ff7-9c4b-9a8d653b9f62"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Modified Root-MUSIC Algorithm", "subitem_subject_scheme": "Other"}, {"subitem_subject": "time-domain filtering", "subitem_subject_scheme": "Other"}, {"subitem_subject": "beamspace Root-MUSIC algorithm", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electromagnetic scattering", "subitem_subject_scheme": "Other"}, {"subitem_subject": "frequency decay parameter", "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": "A Time-Domain Filtering Scheme for the Modified Root-MUSIC Algorithm", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Time-Domain Filtering Scheme for the Modified Root-MUSIC Algorithm"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/21332", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-02-19"}, "publish_date": "2013-02-19", "publish_status": "0", "recid": "1832", "relation": {}, "relation_version_is_last": true, "title": ["A Time-Domain Filtering Scheme for the Modified Root-MUSIC Algorithm"], "weko_shared_id": 2}
