This equipment consists of an optical transmitting and receiving unit and a base-band processong unit. We have studied the base-band unit using an I-Q demodulator and a one-chip microcomputer, which is suitable for realizing smaller size and more flexible operation than a conventional unit. A table look-up method with an I-Q selected-phase-area unequal-interval sampling technique is proposed to detect phase information, which corresponds to snowfall depth. Through analysis using a computer simulation, we show that the proposed method can give the maximum phase-error below 0.5 degrees on a 12-bit A/D converter, even if a receiving signal level has fluctuation of 15 dB. Moreover, we experimentally estimate the phase-error performance by testing the implemented base-band unit.","subitem_description_type":"Abstract"}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟工科大学"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1342-792X","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10590360","subitem_source_identifier_type":"NCID"}]},"item_2_version_type_15":{"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":"田邉, 崇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 栄一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中島, 繁雄"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-25"}],"displaytype":"detail","filename":"niit_95_8_29-35.pdf","filesize":[{"value":"655.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"niit_95_8_29-35.pdf","url":"https://niit.repo.nii.ac.jp/record/104/files/niit_95_8_29-35.pdf"},"version_id":"c19d6f05-4861-47fc-896d-0dcee2cd3811"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"snowfall depth"},{"subitem_subject":"I-Q demodulator"},{"subitem_subject":"phase detection"},{"subitem_subject":"digital signal processing"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"I-Qデモジュレータとマイコンを用いた積雪深計の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"I-Qデモジュレータとマイコンを用いた積雪深計の検討","subitem_title_language":"ja"},{"subitem_title":"A Study on snowfall depth measuring equipment using an I-Q demodulator and a one-chip microcomputer","subitem_title_language":"en"}]},"item_type_id":"2","owner":"4","path":["15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-02-28"},"publish_date":"2011-02-28","publish_status":"0","recid":"104","relation_version_is_last":true,"title":["I-Qデモジュレータとマイコンを用いた積雪深計の検討"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-06-20T05:10:52.284959+00:00"}
