Scope

Cognitive radio is an emerging technology in wireless access, aimed at vastly improving the way radio spectrum is utilized. The motivation for cognitive radio stems from various measurements of spectrum utilization, which generally show that spectrum is under-utilized. This means that there are many “holes” in the radio spectrum that could be exploited by the secondary users. The secondary user must exploit these spectrum opportunities without causing harmful degradation to the primary system. The research challenges in this area include devising methods for efficient spectrum pooling and sensing, and for interference management and dynamic resource allocation as well as circuits and architectures meeting the often challenging requirements.

The aim of this conference is to bring together original, high-quality contributions that present new techniques, concepts and analyses in the area of cognitive radio algorithms and system design. Specific topics of the conference include: spectrum sensing and pooling, network design and optimization, software-defined and flexible radio architectures, channel modeling, cooperative communications, as well as beamforming and multicast methods.
