Résumé:
This paper addresses the problem of energyefficiency
(EE) within an underlay cognitive radio (CR) network
where primary users (PUs) and secondary users (SUs) utilize
two types of multicarrier modulation: orthogonal frequencydivision
multiplexing (OFDM) and filter bank based multicarrier
(FBMC). The problem of non-cooperative SU downlink energyefficiency
is investigated using a game theoretic approach. We
reformulate the EE optimization problem as a non-cooperative
power allocation game (NPAG). A distributed power control
algorithm is proposed to find the optimal power allocation
strategy for each secondary base station on each subcarrier. The
proposed non-cooperative game is demonstrated to reach a Nashequilibrium
(NE) point. Simulation analyses are then provided
in order to validate the efficiency of our proposed distributed
algorithm and also to highlight the advantages of using FBMC
as a modulation technique if compared to OFDM.
