The idea is derived from the concept of unequal scale sampling such that the instantaneous energy statistic of the sampling points in the sensing period is endowed with monotonic weights. The probabilities of false alarm and detection for our ED are deduced under the new detection model. Numerical simulation results show that the proposed ED offers better detection performances with a reduced probability of false alarm compared to conventional ED, and improved energy detector can improve the overall probabilities of detection, when spectrum sensing is performed for a network with high traffic. <\/jats:p>","DOI":"10.1155\/2014\/836793","type":"journal-article","created":{"date-parts":[[2014,3,27]],"date-time":"2014-03-27T07:25:22Z","timestamp":1395905122000},"page":"836793","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Improved Energy Detector with Weights for Primary User Status Changes in Cognitive Radio Networks"],"prefix":"10.1177","volume":"10","author":[{"given":"Xianzhong","family":"Xie","sequence":"first","affiliation":[{"name":"Chongqing Key Lab of Mobile Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}]},{"given":"Xiaofeng","family":"Hu","sequence":"additional","affiliation":[{"name":"Chongqing Key Lab of Mobile Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}]},{"given":"Bin","family":"Ma","sequence":"additional","affiliation":[{"name":"Chongqing Key Lab of Mobile Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}]},{"given":"Ting","family":"Song","sequence":"additional","affiliation":[{"name":"Chongqing Key Lab of Mobile Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}]}],"member":"179","published-online":{"date-parts":[[2014,3,24]]},"reference":[{"key":"B1-2014-836793","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2009.090109"},{"key":"B2-2014-836793","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2011.2158673"},{"key":"B3-2014-836793","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2006.887483"},{"key":"B4-2014-836793","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2010.5403535"},{"key":"B5-2014-836793","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2010.0571"},{"key":"B6-2014-836793","unstructured":"Ahmed S.
