BEP performances are shown. The results obtained are compared with similar results in a channel having flat PDP. Assumption of a flat PDP is found to predict the optimum spreading bandwidth to be lower and sub-optimum operating performance beyond optimum spreading bandwidth to be severely worse than that is achievable in a channel having exponentially decaying PDP by employing an SRake receiver having fixed number of combined paths. Optimum spreading bandwidth for SRake in a channel having exponentially decaying PDP is shown to be much larger than the one in a channel having flat PDP; that is specifically a good-news for UWB communications. Effects of partial band interference are also investigated. Interference is found to be less effective in exponentially decaying PDP.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"5990","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐々木, 重信"}]},{"nameIdentifiers":[{"nameIdentifier":"5991","nameIdentifierScheme":"WEKO"}],"names":[{"name":"村松, 正吾"}]},{"nameIdentifiers":[{"nameIdentifier":"5992","nameIdentifierScheme":"WEKO"}],"names":[{"name":"菊池, 久和"}]}]},"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©2004 IEICE（許諾番号07RB0183）"}]},"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":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rahman, Mohammad Azizur"}],"nameIdentifiers":[{"nameIdentifier":"5985","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Shigenobu"}],"nameIdentifiers":[{"nameIdentifier":"5986","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhou, Jie"}],"nameIdentifiers":[{"nameIdentifier":"5987","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Muramatsu, Shogo"}],"nameIdentifiers":[{"nameIdentifier":"5988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Hisakazu"}],"nameIdentifiers":[{"nameIdentifier":"5989","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":"1_0010.pdf","filesize":[{"value":"521.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1_0010.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1874/files/1_0010.pdf"},"version_id":"7ea86932-1551-45f9-869b-98b731fcbd28"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ultra wideband","subitem_subject_scheme":"Other"},{"subitem_subject":"selective Rake receiver","subitem_subject_scheme":"Other"},{"subitem_subject":"spreading bandwidth","subitem_subject_scheme":"Other"},{"subitem_subject":"power delay profile","subitem_subject_scheme":"Other"},{"subitem_subject":"partial band 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":"Evaluation of selective Rake receiver in direct sequence ultra wideband communications","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of selective Rake receiver in direct sequence ultra wideband communications"},{"subitem_title":"Evaluation of selective Rake receiver in direct sequence ultra wideband communications","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"1874","relation_version_is_last":true,"title":["Evaluation of selective Rake receiver in direct sequence ultra wideband communications"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:41.631215+00:00"}
