The weighted sum of the PU and secondary user (SU) link rates is used as the objective function with constraint on the guaranteed minimum PU link rate. SU with wideband sensing capability selects the idle frequency-slot with the lowest sensed power to be the candidate to access. Numerical results show that the wideband sensing capability with the proposed optimal threshold and accessing strategy can help the SU to meet the stringent PU rate constraints while achieving much higher SU link rate and network capacity.<\/jats:p>","DOI":"10.1186\/1687-1499-2012-360","type":"journal-article","created":{"date-parts":[[2012,12,6]],"date-time":"2012-12-06T03:14:39Z","timestamp":1354763679000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Capacity-maximization threshold design for wideband sensing with guaranteed minimum primary user rate"],"prefix":"10.1186","volume":"2012","author":[{"given":"Peng","family":"Jia","sequence":"first","affiliation":[]},{"given":"Tho","family":"Le-Ngoc","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2012,12,6]]},"reference":[{"issue":"2","key":"518_CR1","doi-asserted-by":"publisher","first-page":"201","DOI":"10.1109\/JSAC.2004.839380","volume":"23","author":"S Haykin","year":"2005","unstructured":"Haykin S: Cognitive radio: brain-empowered wireless communications.
