For the OFDM system, the modulated message data can be demodulated using the partial time-domain OFDM signal. Therefore, the partial time-domain signal can be adopted to reconstruct the whole OFDM time-domain signal with estimated channel information. This property can be utilized to recover packets from the collisions. Since most collisions are cases in which a long packet collides with a short packet, the collided part is assumed to be short. The simulated results show that the method can recover the two collided packets with a certain probability and can be developed to solve the problem of hidden terminals. This method will dramatically benefit the protocol design of wireless networks, including ad hoc and sensor networks.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_2_relation_13": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1093/ietfec/e90-a.7.1312", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_44": {"attribute_name": "関係URI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "http://search.ieice.org/"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://search.ieice.org/", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_14": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright©2007 The Institute of Electronics, Information and Communication Engineers"}]}, "item_2_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826239@@@AA11510296", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0916-8508@@@1745-1337", "subitem_source_identifier_type": "ISSN"}]}, "item_2_version_type_18": {"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": "HOU, Yafei"}], "nameIdentifiers": [{"nameIdentifier": "340", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HAMAMURA, Masanori"}], "nameIdentifiers": [{"nameIdentifier": "341", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "IEICE_E90-A_7_1312.pdf", "filesize": [{"value": "788.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 788600.0, "url": {"label": "IEICE_E90-A_7_1312.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/89/files/IEICE_E90-A_7_1312.pdf"}, "version_id": "66933045-23f2-46f1-aaf9-068ced832773"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "OFDM", "subitem_subject_scheme": "Other"}, {"subitem_subject": "collision recovery", "subitem_subject_scheme": "Other"}, {"subitem_subject": "capture effect", "subitem_subject_scheme": "Other"}, {"subitem_subject": "multipacket reception", "subitem_subject_scheme": "Other"}, {"subitem_subject": "hidden terminals", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ad hoc networks", "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": "Collision Recovery for OFDM System over Wireless Channel", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Collision Recovery for OFDM System over Wireless Channel"}]}, "item_type_id": "2", "owner": "2", "path": ["5"], "permalink_uri": "http://hdl.handle.net/10173/617", "pubdate": {"attribute_name": "公開日", "attribute_value": "2011-01-26"}, "publish_date": "2011-01-26", "publish_status": "0", "recid": "89", "relation": {}, "relation_version_is_last": true, "title": ["Collision Recovery for OFDM System over Wireless Channel"], "weko_shared_id": -1}
