Framework design of CUWB system integrating cognitive radio and UWB

摘要

To solve the problem of increasing radio spectrum scarcity, in this paper, the integration of cognitive radio technology and UWB technology is discussed, and we give the framework design of CUWB system based on the two technologies. In CUWB system, we give the concept of received data reliability, and design the algorithm of received data management decision-making, which provides a new way to address the insufficient spectrum resources,achieve dynamic spectrum management and improve spectrum efficiency.
