To address this issue, an improved energy detection (IED) algorithm based on non\u2010linear parameter\u2010induced stochastic resonator (PSR) is proposed in this study. By adopting the method which combines classic adiabatic approximation stochastic resonance (SR) theory and non\u2010classic parameter\u2010induced SR theory, an analytical expression of SR system parameters is derived. On this basis, a PSR is proposed which is mathematically testified to have the ability to improve the SNR of the received signal. Further, an IED algorithm is proposed by introducing the PSR as the preprocessor of energy detection. Theoretical analyses and simulation results prove that a significantly detection performance and SNR wall improvement can be achieved using the proposed IED algorithm.<\/jats:p>","DOI":"10.1049\/iet-com.2014.0511","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T09:31:36Z","timestamp":1415352696000},"page":"101-107","source":"Crossref","is-referenced-by-count":15,"title":["Lowering the signal\u2010to\u2010noise ratio wall for energy detection using parameter\u2010induced stochastic resonator"],"prefix":"10.1049","volume":"9","author":[{"given":"Jin","family":"Liu","sequence":"first","affiliation":[{"name":"Integrated Service Networks Laboratory Xidian University Xi'an People's Republic of China"}]},{"given":"Zan","family":"Li","sequence":"additional","affiliation":[{"name":"Integrated Service Networks Laboratory Xidian University Xi'an People's Republic of China"}]}],"member":"265","published-online":{"date-parts":[[2015,1]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_8_2_1","DOI":"10.1109\/JSAC.2004.839380"},{"issue":"22","key":"e_1_2_8_3_1","first-page":"1525","article-title":"Cooperative spectrum sensing using particle swarm optimisation","volume":"46","author":"Zheng S.","year":"2010","journal-title":"IET Commun."},{"doi-asserted-by":"publisher","key":"e_1_2_8_4_1","DOI":"10.1109\/97.511809"},{"doi-asserted-by":"publisher","key":"e_1_2_8_5_1","DOI":"10.1109\/TWC.2011.080611.101580"},{"doi-asserted-by":"publisher","key":"e_1_2_8_6_1","DOI":"10.1109\/TCOMM.2009.06.070402"},{"doi-asserted-by":"publisher","key":"e_1_2_8_7_1","DOI":"10.1109\/TCOMM.2006.887483"},{"doi-asserted-by":"publisher","key":"e_1_2_8_8_1","DOI":"10.1109\/JSTSP.2007.914879"},{"doi-asserted-by":"publisher","key":"e_1_2_8_9_1","DOI":"10.1088\/0305-4470\/14\/11\/006"},{"doi-asserted-by":"publisher","key":"e_1_2_8_10_1","DOI":"10.1103\/PhysRevA.39.4854"},{"doi-asserted-by":"publisher","key":"e_1_2_8_11_1","DOI":"10.1016\/S0375-9601(97)00350-2"},{"doi-asserted-by":"publisher","key":"e_1_2_8_12_1","DOI":"10.1142\/S0219477501000408"},{"doi-asserted-by":"publisher","key":"e_1_2_8_13_1","DOI":"10.1103\/PhysRevE.55.2016"},{"doi-asserted-by":"publisher","key":"e_1_2_8_14_1","DOI":"10.1063\/1.166343"},{"doi-asserted-by":"publisher","key":"e_1_2_8_15_1","DOI":"10.1016\/S0960-0779(00)00266-6"},{"doi-asserted-by":"publisher","key":"e_1_2_8_16_1","DOI":"10.1142\/S0218127403006601"},{"doi-asserted-by":"publisher","key":"e_1_2_8_17_1","DOI":"10.1016\/j.physa.2006.10.046"},{"volume-title":"Nonlinear dynamics of chaotic and stochastic systems: tutorial and modern developments","year":"2002","author":"Anishchenko V.S.","key":"e_1_2_8_18_1"}],"container-title":["IET Communications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1049\/iet-com.2014.0511","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1049\/iet-com.2014.0511","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ietresearch.onlinelibrary.wiley.com\/doi\/pdf\/10.1049\/iet-com.2014.0511","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T02:52:30Z","timestamp":1742525550000},"score":1,"resource":{"primary":{"URL":"https:\/\/ietresearch.onlinelibrary.wiley.com\/doi\/10.1049\/iet-com.2014.0511"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,1]]},"references-count":17,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2015,1]]}},"alternative-id":["10.1049\/iet-com.2014.0511"],"URL":"https:\/\/doi.org\/10.1049\/iet-com.2014.0511","archive":["Portico"],"relation":{},"ISSN":["1751-8628","1751-8636"],"issn-type":[{"type":"print","value":"1751-8628"},{"type":"electronic","value":"1751-8636"}],"subject":[],"published":{"date-parts":[[2015,1]]}}}
