MIMO-OFDM systems achieve high-speed and large capacity communications. However, they impose high computational cost in MIMO detection when separating spatially multiplexed signals and they consume vast amounts of power. We propose low-power dynamic MIMO detection that controls detection speed according to wireless environments. The power consumption is reduced by dynamic voltage and frequency scaling (DVFS) that controls the operating voltage and clock frequency in the MIMO detector. We implemented dynamic MIMO detection in a pipelined minimum mean square error (MMSE) MIMO detector that we developed in our previous work. A power saving of 92% was achieved under lowest clock frequency mode conditions.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44844", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "20447080", "nameIdentifierScheme": "KAKEN", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000020447080 "}], "names": [{"name": "吉澤, 真吾", "nameLang": "ja"}]}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Institute of Electronics, Information and Communication Engineers"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1587/transfun.E97.A.306", "subitem_relation_type_select": "DOI"}}]}, "item_3_rights_192": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "c2014 The Institute of Electronics, Information and Communication Engineers"}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_3_subject_196": {"attribute_name": "日本十進分類法", "attribute_value_mlt": [{"subitem_subject": "540", "subitem_subject_scheme": "NDC"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right_uri": "open access"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Miyazaki, Nozomi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "43346", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yoshizawa, Shingo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "43347", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyanaga, Yoshikazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "43348", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2014_IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, E97-A, 1, 306-312.pdf", "filesize": [{"value": "1.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1800000.0, "url": {"label": "2014_IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, E97-A, 1, 306-312.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/8271/files/2014_IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, E97-A, 1, 306-312.pdf"}, "version_id": "4a938664-2290-40d2-be37-388f002a67b0"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "wireless communications", "subitem_subject_scheme": "Other"}, {"subitem_subject": "MIMO detection", "subitem_subject_scheme": "Other"}, {"subitem_subject": "low power", "subitem_subject_scheme": "Other"}, {"subitem_subject": "DVFS", "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": "Low-Power Dynamic MIMO Detection for a 4x4 MIMO- OFDM Receiver", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Low-Power Dynamic MIMO Detection for a 4x4 MIMO- OFDM Receiver", "subitem_title_language": "en"}]}, "item_type_id": "3", "owner": "1", "path": ["87"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/8271", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2016-07-15"}, "publish_date": "2016-07-15", "publish_status": "0", "recid": "8271", "relation": {}, "relation_version_is_last": true, "title": ["Low-Power Dynamic MIMO Detection for a 4x4 MIMO- OFDM Receiver"], "weko_shared_id": -1}
