The Research of Cross-Layer Architecture Design for MCM-Based Cognitive Radio Network

In this paper, we discuss the framework of MCM-Based cognitive radio network (MCM-Based CRN) and motivations for cross-layer design in CRN first. Moreover, we proposed a novel architecture in which the dynamic channel allocation is achieved by a cross-layer design between the PHY and MAC layers for MCM-Based cognitive radio network. Finally, A OFDM-Based cognitive radio transmitter and receiver is proposed.
