To support this spectrum reuse functionality, the SU is required to sense each subchannel, and only the subchannels wherein the PU is inactive are available for the spectrum access of the SU. In this paper, a multislot spectrum sensing and transfer scheme for multichannel CR is proposed, whose sensing stage is divided into several time slots allocated to the subchannels for spectrum sensing. While guaranteeing the spectrum sensing performance on each subchannel and limiting the interference to the PU, we formulate an optimization problem that maximizes the SU\u2019s aggregate throughput by jointly allocating the optimal number of sensing time slots and the optimal transfer power to each subchannel. Theoretical analysis is given to prove the feasibility of the proposed optimization problem and simulation results are presented to show the notable improvement on the SU\u2019s throughput when the sensing time slots and the transfer power are both optimized by the proposed scheme.<\/jats:p>","DOI":"10.1155\/2014\/494361","type":"journal-article","created":{"date-parts":[[2014,8,21]],"date-time":"2014-08-21T22:55:27Z","timestamp":1408661727000},"page":"1-9","source":"Crossref","is-referenced-by-count":7,"title":["Optimal Joint Allocation of MultiSlot Spectrum Sensing and Transfer Power in MultiChannel Cognitive Radio"],"prefix":"10.1155","volume":"2014","author":[{"given":"Xin","family":"Liu","sequence":"first","affiliation":[{"name":"College of Astronautics, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"},{"name":"Communication Research Centre, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Jia","sequence":"additional","affiliation":[{"name":"Communication Research Centre, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuemai","family":"Gu","sequence":"additional","affiliation":[{"name":"Communication Research Centre, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fanqiang","family":"Kong","sequence":"additional","affiliation":[{"name":"College of Astronautics, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingfeng","family":"Jing","sequence":"additional","affiliation":[{"name":"College of Astronautics, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.telpol.2012.07.003"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/MVT.2012.2190219"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/s11265-013-0765-z"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2013.6507397"},{"issue":"11","key":"5","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1109\/CC.2013.6674212","volume":"10","year":"2013","journal-title":"China Communications"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2011.102011.100708"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.3390\/s130405251"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2013.040213.120781"},{"issue":"3","key":"9","doi-asserted-by":"crossref","first-page":"1128","DOI":"10.1109\/TWC.2010.03.090467","volume":"9","year":"2010","journal-title":"IEEE Transactions on Wireless Communications"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2008.2008540"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2008.060869"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2009.2028030"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/606413"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/349389"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2014\/494361.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2014\/494361.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2014\/494361.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,12]],"date-time":"2020-05-12T04:58:05Z","timestamp":1589259485000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/js\/2014\/494361\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":14,"alternative-id":["494361","494361"],"URL":"https:\/\/doi.org\/10.1155\/2014\/494361","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2014]]}}}
