Identification of IEEE 802 CR systems for heterogeneous coexistence on TV white space

Recently, the IEEE 802 working groups for regional, local, metropolitan, and personal area networks undertake standardization of cognitive radio (CR) networks exploiting TV white spaces. Thus, in the near future, various types of IEEE 802 CR systems may operate on the same TV channel simultaneously. A CR system can coexist more effectively with other CR systems on the same TV channel if it can identifies the types of them. In this paper we propose a system identification scheme for distinguishing the coexisting IEEE 802 CR networks, which exploits the unique features of each system. Simulation results show that the proposed scheme identifies IEEE 802 CR systems accurately and efficiently.
