One of the most typical channel identification schemes is to employ a code division multiplexing (CDM) based scheme in which a unique spreading code is assigned to distinguish both BS and MS antenna elements. However, by increasing the number of base stations and transmit antenna elements, large spreading codes and pilot symbols are required to distinguish the received power from all the connectable BS, as well as to identify all the CSI for the combination of transmitter and receiver antenna elements. Furthermore, the complexity of maximum likelihood detection (MLD) for implementation of MIMO is a considerable work. To reduce these problems, in this paper, we propose the parallel detection algorithm using multiple QR decompositions with permuted channel matrix (MQRD-PCM) with discrete pilot signal assignment and iterative channel identification for MIMO/OFDM.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会(IEICE)"}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.ieice.org/jpn/trans_online/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/trans_online/","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright©2008 IEICE"}]},"item_10001_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_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1745-1337(online)|0916-8508(print)","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"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":"AHN, Chang-Jun"},{"creatorName":"アン, チャンジュン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安, 昌俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4485","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":"2023-02-28"}],"displaytype":"detail","filename":"E91A2000.pdf","filesize":[{"value":"570.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"E91A2000.pdf","url":"https://hiroshima-cu.repo.nii.ac.jp/record/1303/files/E91A2000.pdf"},"version_id":"c0587a66-10e3-4ad7-969b-eed11d4a23b7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MIMO","subitem_subject_scheme":"Other"},{"subitem_subject":"OFDM","subitem_subject_scheme":"Other"},{"subitem_subject":"QR decomposition","subitem_subject_scheme":"Other"},{"subitem_subject":"MQRD-PCM","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":"Throughput Improvement with Discrete Pilot Signal Assignment and Iterative Channel Identification for MQRD-PCM/OFDM","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Throughput Improvement with Discrete Pilot Signal Assignment and Iterative Channel Identification for MQRD-PCM/OFDM"}]},"item_type_id":"10001","owner":"1","path":["210"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-02-28"},"publish_date":"2023-02-28","publish_status":"0","recid":"1303","relation_version_is_last":true,"title":["Throughput Improvement with Discrete Pilot Signal Assignment and Iterative Channel Identification for MQRD-PCM/OFDM"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-07-25T10:47:50.839015+00:00"}
