In the propose method, second antenna receives the signals while first antenna transmits the preamble signals. Hence, the interference can be detected by observing the subcarriers which are not mapped short preamble signal using the received signal after the FFT processing. Moreover, we utilize the orthogonal polarized antennas to reduce the mutual coupling between the transmitter and receiver. By a computer simulation and measurement with the use of orthogonal polarized antenna, it is shown that the proposed method can successfully detect interference from the other system when the interfering power is greater than the noise power.","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_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1587/comex.2.307","subitem_relation_type_select":"DOI"}}]},"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":"https://www.jstage.jst.go.jp/","subitem_relation_type_select":"URI"}},{"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)2013 IEICE"},{"subitem_rights":"本文データは学協会の許諾に基づきJ-Stage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_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21870136","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kataoka, Ryochi"}],"nameIdentifiers":[{"nameIdentifier":"5405","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishimori, Kentaro"}],"nameIdentifiers":[{"nameIdentifier":"5406","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuwahara, Masaaki"}],"nameIdentifiers":[{"nameIdentifier":"5407","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiraguri, Takefumi"}],"nameIdentifiers":[{"nameIdentifier":"5408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makino, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"5409","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":"2_7_307-312.pdf","filesize":[{"value":"767.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2_7_307-312.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1749/files/2_7_307-312.pdf"},"version_id":"b90b93cc-0262-43d9-99d3-760c0b6d438c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MIMO","subitem_subject_scheme":"Other"},{"subitem_subject":"collision detection","subitem_subject_scheme":"Other"},{"subitem_subject":"short preamble signals","subitem_subject_scheme":"Other"},{"subitem_subject":"orthogonal polarized antennas","subitem_subject_scheme":"Other"},{"subitem_subject":"interference","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":"Interference detection method using wireless LAN based MIMO transmission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Interference detection method using wireless LAN based MIMO transmission"},{"subitem_title":"Interference detection method using wireless LAN based MIMO transmission","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-02"},"publish_date":"2014-12-02","publish_status":"0","recid":"1749","relation_version_is_last":true,"title":["Interference detection method using wireless LAN based MIMO transmission"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:33.732026+00:00"}
