In this system, both systems share the same frequency band to improve the spectrum efficiency. Overall rate, bit error ratio (BER) and spectrum efficiency of the system are calculated for the forward link (downlink) in the presence of AWGN channel. Taking into account the path loss and shadow fading loss in this system with cellular architecture, W-CDMA applying interference cancellation (IC) shows a substantial difference in spectrum efficiency, the overlaid system can provide a greater overall rate and higher spectrum efficiency than a single multiple access-based system such as TDMA system or W-CDMA system. The interference cancellation can significantly improve BER of the spectrum overlaid system.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "6046", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "菊池, 久和"}]}, {"nameIdentifiers": [{"nameIdentifier": "6047", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "佐々木, 重信"}]}, {"nameIdentifiers": [{"nameIdentifier": "6048", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "村松, 正吾"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright©2002 IEICE（許諾番号07RB0183）"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_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_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168508", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Zhou, Jie"}], "nameIdentifiers": [{"nameIdentifier": "6041", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kikuchi, Hisakazu"}], "nameIdentifiers": [{"nameIdentifier": "6042", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sasaki, Shigenobu"}], "nameIdentifiers": [{"nameIdentifier": "6043", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Muramatsu, Shogo"}], "nameIdentifiers": [{"nameIdentifier": "6044", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Onozato, Yoshikuni"}], "nameIdentifiers": [{"nameIdentifier": "6045", "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": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "1_0018.pdf", "filesize": [{"value": "650.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 650500.0, "url": {"label": "1_0018.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1882/files/1_0018.pdf"}, "version_id": "4b2afaad-4c88-4678-a502-dd65a4b05279"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "code-division multiple access (CDMA)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "time-division multiple access (TDMA)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "TDMA", "subitem_subject_scheme": "Other"}, {"subitem_subject": "W-CDMA overlaid system", "subitem_subject_scheme": "Other"}, {"subitem_subject": "notch filter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "signal clipper", "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": "Forward Link Performance of TDMA/W-CDMA Spectrum Overlaid System with Interference Cancellation for Future Wireless Communications", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Forward Link Performance of TDMA/W-CDMA Spectrum Overlaid System with Interference Cancellation for Future Wireless Communications"}, {"subitem_title": "Forward Link Performance of TDMA/W-CDMA Spectrum Overlaid System with Interference Cancellation for Future Wireless Communications", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/6212", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "1882", "relation": {}, "relation_version_is_last": true, "title": ["Forward Link Performance of TDMA/W-CDMA Spectrum Overlaid System with Interference Cancellation for Future Wireless Communications"], "weko_shared_id": null}
