A modification of the MUSIC algorithm is employed to resolve incident signals separately in the time domain. The modification involves preprocessing the received data using a spatial scheme prior to applying the MUSIC algorithm. Interference rejection in the antenna measurements using the fast Fourier transform (FFT) based techniques have been realized by a recently developed vector network analyzer, and its availability has been reported in the literature. However, response resolution in the time domain of these conventional techniques is limited by the antenna bandwidth. The MUSIC algorithm has the advantage of being able to eliminate unwanted responses when performing antenna measurements in situations where the antenna bandwidth is too narrow to support FFT based techniques. In this paper, experimental results of antenna gain measurements in a multipath environment show the accuracy and resolving power of this technique.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"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"}},{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003216984","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 1993 IEICE"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"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":"Ogawa, Yasutaka"}],"nameIdentifiers":[{"nameIdentifier":"5819","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itoh, Kiyohiko"}],"nameIdentifiers":[{"nameIdentifier":"5820","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","filename":"110003216984.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110003216984.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1839/files/110003216984.pdf"},"version_id":"73b73270-2178-4380-bbd7-c226ed9a4905"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"antenna gain measurements","subitem_subject_scheme":"Other"},{"subitem_subject":"multipath environments","subitem_subject_scheme":"Other"},{"subitem_subject":"MUSIC algorithm","subitem_subject_scheme":"Other"},{"subitem_subject":"spatial smoothing preprocessing","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":"Antenna Gain Measurements in the Presence of Unwanted Multipath Signals Using a Superresolution Technique","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Antenna Gain Measurements in the Presence of Unwanted Multipath Signals Using a Superresolution Technique"},{"subitem_title":"Antenna Gain Measurements in the Presence of Unwanted Multipath Signals Using a Superresolution Technique","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-27"},"publish_date":"2013-08-27","publish_status":"0","recid":"1839","relation_version_is_last":true,"title":["Antenna Gain Measurements in the Presence of Unwanted Multipath Signals Using a Superresolution Technique"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:41.266450+00:00"}
