基于差分进化算法的认知无线电频谱分配
Spectrum allocation based on differential evolution algorithm in cognitive radio
摘要
Abstract
According to the problem of spectrum allocation for secondary users in cognitive radio system, this paper puts forward the spectrum allocation algorithm based on the differential evolution algorithm. With less parameters, strong ability of finding global optimization solution and avoiding getting into local optimality of the differential evolution algorithm. The spectrum allocation scheme is got which can maximize the mean system utility. The simulation results show that the algorithm in this paper not only increases mean system utility of secondary users but also shortens running time and improves the efficiency of spectrum allocation.关键词
