Our objective is to find the maximum number of admitted secondary links and then find the optimal transmitting powers and code sequences of those secondary links such that the total energy consumption of the secondary network is minimized subject to the conditions that primary interference temperature constraints, secondary signal-to-interference-plus-noise ratio (SINR) constraints and secondary peak power constraints are all satisfied. This is an NP-hard optimization problem which motivates the development of suboptimal algorithms. We propose a novel iterative algorithm to solve this problem in a computationally efficient manner. Numerical results demonstrate that the proposed algorithm provides excellent solutions that result in high energy efficiency and large admitted percentage of secondary links.<\/jats:p>","DOI":"10.1155\/2012\/510942","type":"journal-article","created":{"date-parts":[[2012,9,12]],"date-time":"2012-09-12T18:02:47Z","timestamp":1347472967000},"page":"1-9","source":"Crossref","is-referenced-by-count":2,"title":["Cognitive Code-Division Channelization with Admission Control"],"prefix":"10.1155","volume":"2012","author":[{"given":"Kanke","family":"Gao","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, NY 14260, USA"}]},{"given":"Onur","family":"Ozdemir","sequence":"additional","affiliation":[{"name":"ANDRO Computational Solutions, 7902 Turin Road Bldg. 2, Rome, NY 13440, USA"}]},{"given":"Dimitris A.","family":"Pados","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, NY 14260, USA"}]},{"given":"Stella N.","family":"Batalama","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, NY 14260, USA"}]},{"given":"Tommaso","family":"Melodia","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, NY 14260, USA"}]},{"given":"Andrew L.","family":"Drozd","sequence":"additional","affiliation":[{"name":"ANDRO Computational Solutions, 7902 Turin Road Bldg. 2, Rome, NY 13440, USA"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2007.361604"},{"key":"3","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1109\/TCOMM.2011.100411.100242","volume":"60","year":"2012","journal-title":"IEEE Transactions on Communications"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/25.260747"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/25.406608"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/BF01098870"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1049\/el:19940140"},{"issue":"1","key":"8","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1007\/BF01201460","volume":"2","year":"1996","journal-title":"Wireless Networks"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2007.50"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/T-WC.2008.070890"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2011.011811.091542"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1002\/wcm.724"},{"key":"14","doi-asserted-by":"crossref","first-page":"3743","DOI":"10.1109\/TWC.2011.091911.101260","volume":"10","year":"2011","journal-title":"IEEE Transaction on Wireless Communications"},{"year":"2001","key":"17"},{"year":"2004","key":"15"},{"year":"2001","key":"16"},{"year":"1973","key":"18"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2002.807628"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1023\/A:1024759310058"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2004.823428"}],"container-title":["Journal of Computer Networks and Communications"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2012\/510942.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2012\/510942.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2012\/510942.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,20]],"date-time":"2017-06-20T20:06:14Z","timestamp":1497989174000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jcnc\/2012\/510942\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":19,"alternative-id":["510942","510942"],"URL":"https:\/\/doi.org\/10.1155\/2012\/510942","relation":{},"ISSN":["2090-7141","2090-715X"],"issn-type":[{"type":"print","value":"2090-7141"},{"type":"electronic","value":"2090-715X"}],"subject":[],"published":{"date-parts":[[2012]]}}}
