Radio spectrum is becoming exhausted because of the growing demands for wireless broadband communications. To cope this problem, the paradigm shift from the conventional exclusive use of frequency resources to the flexible frequency utilization is indispensable for future wireless networks. Cognitive radio is a key technology that brings us an emerging paradigm of flexible frequency spectrum usage. By cognition of the radio frequency environment, cognitive radio terminals dynamically select the optimal frequency and transmission media with cooperation of networks. In these regards, this conference provides opportunities for researchers in both academia and industry to present the latest technologies and exchange ideas in the area of cognitive radio. The following topics are welcome to this conference.
