    • Optimal power allocation in dispersed cognitive radio systems with carrier aggregation 

      Foukalas, Fotis; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, we investigate the optimal power allocation problem in dispersed cognitive radios with carrier aggregation. To this end, we model the carrier aggregation using an i - th frequency diversity policy, wherein ...
