In this paper, we propose an improved approach as sparse learning via iterative minimization based on compressive sampling (CS-SLIM) for wideband spectrum detection. CS-SLIM can provide wideband spectrum detection with almost the same accuracy but a lower computational burden than that of SLIM. The measurement matrix and the computational complexity for CS-SLIM are discussed. Mean squared errors (MSEs) at various measurement samples are provided to demonstrate the performance of the proposed approach in sparse scenes. It is also proved that the algorithm is suitable for sparse signal reconstruction and wideband spectrum sensing in C-WSN. <\/jats:p>","DOI":"10.1155\/2013\/261953","type":"journal-article","created":{"date-parts":[[2013,5,25]],"date-time":"2013-05-25T21:00:25Z","timestamp":1369515625000},"page":"261953","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Cooperative Spectrum Sensing Algorithm Based on CS-SLIM Iterative Minimization Sparse Learning"],"prefix":"10.1177","volume":"9","author":[{"given":"Ning","family":"Cao","sequence":"first","affiliation":[{"name":"College of Computer and Information, Hohai University, Nanjing, Jiangsu 210098, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2753-2085","authenticated-orcid":false,"given":"Xiaowen","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Computer and Information, Hohai University, Nanjing, Jiangsu 210098, China"}]},{"given":"Hao","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Computer and Information, Hohai University, Nanjing, Jiangsu 210098, China"}]},{"given":"Minghe","family":"Mao","sequence":"additional","affiliation":[{"name":"College of Computer and Information, Hohai University, Nanjing, Jiangsu 210098, China"}]}],"member":"179","published-online":{"date-parts":[[2013,5,25]]},"reference":[{"first-page":"772","volume-title":"Proceedings of the 38th Asilomar Conference on Signals, Systems and Computers","author":"Cabric D.","key":"B1-2013-261953"},{"key":"B2-2013-261953","doi-asserted-by":"publisher","DOI":"10.1109\/DYSPAN.2005.1542650"},{"key":"B3-2013-261953","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2006.887483"},{"key":"B4-2013-261953","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2010.100110.100473"},{"key":"B5-2013-261953","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2010.2051327"},{"key":"B6-2013-261953","doi-asserted-by":"publisher","DOI":"10.1137\/S1064827596304010"},{"key":"B7-2013-261953","doi-asserted-by":"publisher","DOI":"10.1109\/78.258082"},{"first-page":"40","volume-title":"Proceedings of the 27th Asilomar Conference on Signals, Systems & Computers","author":"Pati Y.
