Research on Energy Efficiency Priority for Spectrum Sensing Algorithm In Cognitive Radio
摘要
Abstract
Spectrum sensing is one of the key technologies in cognitive radio(CR).An energy-efficient spectrum sensing algorithm based on sensing performance is investigated to reduce the spectrum sensing energy in cognitive radio.Firstly,the sensing energy consumption minimization is modeled.Then,the relationship between the target detection probability and the minimum sensing energy consumption is derived,and the minimum sensing energy consumption under the target detection probability is given.Finally,the algorithm is simulated in cognitive radio of single-channel and multi-channel and the simulation results validate the theoretical derivation.关键词
