We investigate the blind adaptive decorrelating detector (BADD) using only the signature of the desired user (DU) according to the assumption that the algorithm is used in downlink. When the BADD is constructed with an antenna array, both the spatial and temporal signature must be taken into consideration for signal detection. We propose the BADD incorporated with the blind estimation of spatial signature (SS) of the DU only from the received signals. As the estimation procedure of SS, the orthogonal projection approximation and subspace tracking algorithm is adopted. The proposed BADD presented the BER improvement with using antenna array. The BER performance has a lower limit with increasing the number of antenna array elements.", "subitem_description_type": "Abstract"}]}, "item_3_description_185": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Copyright (c) 2008 IEICE", "subitem_description_type": "Other"}]}, "item_3_description_194": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers (IEICE)"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1093/ietfec/e89-a.10.2686", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "KIMURA, Yuji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "37341", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SHIBATA, Koji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "37342", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SAKAI, Takakazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "37343", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NAKAGAKI, Atsushi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "37344", "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": "ieice_e89a_2686-2689.pdf", "filesize": [{"value": "405.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 405100.0, "url": {"label": "ieice_e89a_2686-2689.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/7283/files/ieice_e89a_2686-2689.pdf"}, "version_id": "db212045-8dee-4002-baef-ff818364077a"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "blind adaptive decorrelating detector", "subitem_subject_scheme": "Other"}, {"subitem_subject": "antenna array", "subitem_subject_scheme": "Other"}, {"subitem_subject": "spatial and temporal signature", "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": "A Blind Adaptive Decorrelating Detector Using Spatial Signature Estimation", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Blind Adaptive Decorrelating Detector Using Spatial Signature Estimation", "subitem_title_language": "en"}]}, "item_type_id": "3", "owner": "1", "path": ["87"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/7283", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-03-17"}, "publish_date": "2008-03-17", "publish_status": "0", "recid": "7283", "relation": {}, "relation_version_is_last": true, "title": ["A Blind Adaptive Decorrelating Detector Using Spatial Signature Estimation"], "weko_shared_id": -1}
