In this study, we experimentally perform the reception of BPSK (Binary Phase Shift Keying)/ OFDM (Orthogonal Frequency Division Multiplexing) signals using additional noise and 1bit ADCs. We use an arbitrary function generator to generate BPSK/OFDM signals, a noise generator to generate wide-band white noise, and high-speed ADC and data capture board. The data obtained by the capture board is applied to 1bit ADCs realized by software. We apply moving average filter and Hamming windowing to 1bit ADC output to evaluate the expected value of the 1bit ADC input signal. BER (Bit Error Rate) performances for variable noise attenuation verified that 128 bits of transmitted data can be demodulated without error for sufficiently small noise. This tendency is different from the previous studies in the framework of stochastic resonance.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"一般社団法人　電子情報通信学会"},{"subitem_1522300295150":"en","subitem_1522300316516":"THE INSTITUTE OF ELECTRONICS, INFORMATION AND COMMUNICATION ENGINEERS"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"PISSN","subitem_1522646572813":"0913-5685"},{"subitem_1522646500366":"EISSN","subitem_1522646572813":"2432-6380"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"電子情報通信学会技術研究報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"IEICE Technical Report"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2022-06-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"73","bibliographicPageEnd":"241","bibliographicPageStart":"236","bibliographicVolumeNumber":"122"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-09-05"}],"filename":"齋藤　将人-10131027-RCS2022-64(1bit_ADCを用いたOFDM信号受信実験).pdf","filesize":[{"value":"1.1 MB"}],"url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2019437/files/齋藤　将人-10131027-RCS2022-64(1bit_ADCを用いたOFDM信号受信実験).pdf"},"version_id":"8a5adb01-3394-4016-b09f-7843e5aa9f71"}]},"item_title":"1bit ADCを用いたOFDM信号受信実験","item_type_id":"59","owner":"8","path":["1642838338003","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-09-05"},"publish_date":"2022-09-05","publish_status":"0","recid":"2019437","relation_version_is_last":true,"title":["1bit ADCを用いたOFDM信号受信実験"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-08-03T05:34:45.848098+00:00"}
