In those systems, the performance improvement on cell-edge users is crucial to provide high-speed services. We propose a new resource allocation scheme based on multiple input multiple output ? orthogonal frequency division multiple access ? code division multiplexing (MIMO-OFDMA-CDM) to achieve performance improvements in terms of cell-edge user throughput, bit error rate, and fairness among users. The proposed scheme adopts code division multiplexing for MIMO-OFDMA and a modified proportional fairness algorithm for CDM, which enables the fairness among users and a higher throughput. The performance improvements are clarified by theoretical analysis and simulations.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"不破, 康宏"}]},{"nameIdentifiers":[{},{}],"names":[{"name":"岡本, 英二"}]},{"nameIdentifiers":[{}],"names":[{"name":"岩波, 保則"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers"}]},"item_10001_relation_37":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://search.ieice.org/bin/summary.php?id=e94-b_12_3550&category=B&lang=E&year=2011&abst="}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://search.ieice.org/bin/summary.php?id=e94-b_12_3550&category=B&lang=E&year=2011&abst=","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168516","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fuwa, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Iwanami, Yasunori","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-26"}],"displaytype":"detail","filename":"e94-b_12_3550.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","license_note":"Copyright(C) 2011 IEICE http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5589/files/e94-b_12_3550.pdf"},"version_id":"419956f9-e5a2-44a5-b235-9cc64ef7525a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"OFDMA-CDM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MIMO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cellular system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resource allocation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"proportional fairness","subitem_subject_language":"en","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":"An Effective Downlink Resource Allocation Scheme Based on MIMO-OFDMA-CDM in Cellular System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Effective Downlink Resource Allocation Scheme Based on MIMO-OFDMA-CDM in Cellular System","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-07-31"},"publish_date":"2013-07-31","publish_status":"0","recid":"5589","relation_version_is_last":true,"title":["An Effective Downlink Resource Allocation Scheme Based on MIMO-OFDMA-CDM in Cellular System"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T13:32:17.164718+00:00"}
