Cognitive wireless cloud : A network concept to handle heterogeneous and spectrum sharing type radio access networks

This paper introduces a network concept to handle heterogeneous and spectrum sharing (white space) type radio access networks, cognitive wireless cloud (CWC). This paper explains the overview, the system architecture, and the feasibility studies. As for the feasibility studies, network implementation and the development of new base station and terminal that suit for the CWC have done by using the technologies of cognitive radio and software defined radio technologies.
