Prime focus is made on the coarse detection part for interweaved system, in which unoccupied spectrum can be used efficiently by the cognitive users. Quick and immediate shifting over the sensed vacant channel is extremely vital and is a challenging task. To overcome this issue, fast and efficient spectrum sensing technique is proposed for cognitive radios by improvising the Discrete Wavelet Packet Transform (DWPT) for multiresolution interweaved systems. This proposed scheme not only increases the system speed but also reduces complexity. Simulation results are used to analyse the system performance and numerical analysis for computing system complexity.<\/jats:p>","DOI":"10.1155\/2018\/1908536","type":"journal-article","created":{"date-parts":[[2018,7,29]],"date-time":"2018-07-29T23:30:41Z","timestamp":1532907041000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Advanced Multiresolution Wavelet Based Wideband Spectrum Sensing Technique for Cognitive Radio"],"prefix":"10.1155","volume":"2018","author":[{"given":"Jai Sukh Paul","family":"Singh","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1724-0636","authenticated-orcid":false,"given":"Mritunjay Kumar","family":"Rai","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0026-149X","authenticated-orcid":false,"given":"Gulshan","family":"Kumar","sequence":"additional","affiliation":[]},{"given":"Rajwinder","family":"Singh","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6705-4423","authenticated-orcid":false,"given":"Hye-Jin","family":"Kim","sequence":"additional","affiliation":[]},{"given":"Tai-hoon","family":"Kim","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2018,7,29]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/98.788210"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.phycom.2017.08.007"},{"key":"e_1_2_9_3_2","article-title":"Cumulant-based blind cooperative spectrum sensing method for cognitive radio","author":"Jun W.","year":"2017","journal-title":"Physical Communication"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-014-2088-1"},{"key":"e_1_2_9_5_2","unstructured":"FCC Spectrum Policy Task Force Second report and order Federal Communications Commission IEEE Report on Unlicensed Operation in the TV Broadcast Bands 2002 no.
