Impact of emission constraints on direct sequence (DS-) UWB communications that use arbitrary chip-duty is discussed in this letter. Depending on the communication pulse shape, a minimum chip-duty below which average emission cannot be increased with bandwidth, or in other words, permissible average emission limit cannot be reached due to the peak constraint is pointed. Effect of the emission constraints on the system capacity is also investigated and compared with the same with no constraint. It is shown that a peak constraint slows down the capacity increment with bandwidth.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"5441","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐々木, 重信"}]},{"nameIdentifiers":[{"nameIdentifier":"5442","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_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1587/elex.1.483","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":"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_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13492543","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rahman, Mohammad Azizur"}],"nameIdentifiers":[{"nameIdentifier":"5437","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Shigenobu"}],"nameIdentifiers":[{"nameIdentifier":"5438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhou, Jie"}],"nameIdentifiers":[{"nameIdentifier":"5439","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Hisakazu"}],"nameIdentifiers":[{"nameIdentifier":"5440","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_0009.pdf","filesize":[{"value":"219.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1_0009.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1756/files/1_0009.pdf"},"version_id":"038a90dc-b5fc-4926-beef-ca8e67e28aca"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ultra wideband","subitem_subject_scheme":"Other"},{"subitem_subject":"emission constraints","subitem_subject_scheme":"Other"},{"subitem_subject":"chip-duty","subitem_subject_scheme":"Other"},{"subitem_subject":"capacity","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":"Impact of emission constraints on DS-UWB communications with arbitrary chip-duty","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact of emission constraints on DS-UWB communications with arbitrary chip-duty"},{"subitem_title":"Impact of emission constraints on DS-UWB communications with arbitrary chip-duty","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":"1756","relation_version_is_last":true,"title":["Impact of emission constraints on DS-UWB communications with arbitrary chip-duty"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:33.493017+00:00"}
