A check node stopping (CNS) scheme is used to tag reliability of check nodes by detecting the magnitudes of the check node belief messages with a threshold. The operation of reliable check nodes tagged by the CNS scheme can be stopped in the later iterations. The proposed LDPC decoder that employs the CNS scheme can significantly terminate the redundant operations of check nodes and efficiently reduce the power consumption of decoder. From the simulations under WiMAX QC LDPC decoding with high channel quality, the CNS scheme achieves up to 12% stopping rate of check nodes with a loss of coding gain less than 0.1 dB. The WiMAX QC LDPC decoder chip that employs the CNS scheme is implemented by a 90-nm CMOS process. Compared with the LDPC decoder that employs no CNS scheme, the overall power dissipation of the proposed LDPC decoder is decreased by 4.1% with 0.5% area overhead. <\/jats:p>","DOI":"10.1142\/s0218126617500281","type":"journal-article","created":{"date-parts":[[2016,9,19]],"date-time":"2016-09-19T03:36:24Z","timestamp":1474256184000},"page":"1750028","source":"Crossref","is-referenced-by-count":3,"title":["Design and Implementation of Operation-Reduced LDPC Decoder Based on a Check Node Stopping Scheme"],"prefix":"10.1142","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8373-2271","authenticated-orcid":false,"given":"Cheng-Hung","family":"Lin","sequence":"first","affiliation":[{"name":"Innovation Center for Big Data and Digital Convergence, Yuan Ze University, 135 Yuan-Jung Road, Chung-Li, Taiwan 32003, Republic of China"},{"name":"Department of Electrical Engineering, Yuan Ze University, 135 Yuan-Tung Road, Chung-Li, Taiwan 32003, Republic of China"}]},{"given":"Tzu-Hsuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Yuan Ze University, 135 Yuan-Tung Road, Chung-Li, Taiwan 32003, Republic of China"}]},{"given":"Shu-Yen","family":"Lin","sequence":"additional","affiliation":[{"name":"Innovation Center for Big Data and Digital Convergence, Yuan Ze University, 135 Yuan-Jung Road, Chung-Li, Taiwan 32003, Republic of China"},{"name":"Department of Electrical Engineering, Yuan Ze University, 135 Yuan-Tung Road, Chung-Li, Taiwan 32003, Republic of China"}]},{"given":"Yu-Hsuan","family":"Lee","sequence":"additional","affiliation":[{"name":"Innovation Center for Big Data and Digital Convergence, Yuan Ze University, 135 Yuan-Jung Road, Chung-Li, Taiwan 32003, Republic of China"},{"name":"Department of Electrical Engineering, Yuan Ze University, 135 Yuan-Tung Road, Chung-Li, Taiwan 32003, Republic of China"}]}],"member":"219","published-online":{"date-parts":[[2016,11,3]]},"reference":[{"key":"S0218126617500281BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.1962.1057683"},{"key":"S0218126617500281BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/18.748992"},{"key":"S0218126617500281BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/4.987093"},{"key":"S0218126617500281BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/TVLSI.2003.817545"},{"key":"S0218126617500281BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2004.836563"},{"key":"S0218126617500281BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2008.916606"},{"key":"S0218126617500281BIB011","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2007.916610"},{"key":"S0218126617500281BIB012","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126613500394"},{"key":"S0218126617500281BIB013","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126615500267"},{"key":"S0218126617500281BIB014","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2009.2027967"},{"key":"S0218126617500281BIB015","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cds.2014.0347"},{"key":"S0218126617500281BIB016","doi-asserted-by":"publisher","DOI":"10.1109\/JLT.2015.2477881"},{"key":"S0218126617500281BIB017","doi-asserted-by":"publisher","DOI":"10.1109\/TVLSI.2009.2025169"},{"key":"S0218126617500281BIB018","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2014.2300417"},{"key":"S0218126617500281BIB019","doi-asserted-by":"publisher","DOI":"10.1049\/el.2013.1843"},{"key":"S0218126617500281BIB022","doi-asserted-by":"publisher","DOI":"10.1049\/el.2012.2625"},{"key":"S0218126617500281BIB025","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2004.838370"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126617500281","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T05:45:54Z","timestamp":1569217554000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126617500281"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,11,3]]},"references-count":17,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2016,11,3]]},"published-print":{"date-parts":[[2017,2]]}},"alternative-id":["10.1142\/S0218126617500281"],"URL":"https:\/\/doi.org\/10.1142\/s0218126617500281","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"type":"print","value":"0218-1266"},{"type":"electronic","value":"1793-6454"}],"subject":[],"published":{"date-parts":[[2016,11,3]]}}}
