| Popis: | In this paper, we discuss the framework of cognitive radio network and OFDMA technology first, and analysis the motivations for cross-layer design in cognitive radio network (CRN). Moreover, we proposed the OFDMA-Based cognitive radio transceiver. Finally, a novel architecture in which the dynamic channel allocation is achieved by a cross-layer design between the PHY and MAC layers for OFDMA-Based cognitive radio network is proposed. The optimization of joint power control and link scheduling on the cross-layer architecture of OFDMA-based CRN has been simulated. Simulation shows it can improve network performance. |
