Dynamic Spectrum Access: From the Concept to the Implementation

Call for Papers

We are today witnessing an explosive growth in the deployment of wireless communication services. At the same time, wireless system designers are facing the continuously increasing demand for capacity and mobility required by the new user applications. The scarcity of the radio spectrum, densely allocated by the regulators, is a major bottleneck in the development of new wireless communications systems. However actual spectrum occupancy measurements show that the frequency band scarcity is not a result of the heavy usage of the spectrum, but is rather due to the inefficient static frequency allocation pursued by the regulators.

Dynamic spectrum access has been proposed as a new technology to resolve this paradox. Sparse assigned frequency bands are opened to secondary users, provided that interference generated on the primary licensee is negligible. Even if the concept constitutes a real paradigm shift, it is still unclear how the dynamic spectrum access can operate efficiently and how it can be implemented cost-effectively.

Scope. Original contributions are solicited in all aspects of dynamic spectrum access related to the integration of the technology in a real communication system. The special issue should give clear advice on how to make dynamic spectrum access work in practice. Topics of interest include, but are not limited to:

• Spectrum sensing and access:
  • Spectrum sensing mechanisms and protocol support
  • Interference modeling and avoidance
  • Adaptive coding and modulation for interference avoidance
  • Beamforming and MIMO for interference avoidance
  • Distributed cooperative spectrum sensing and communication
  • Ultra-wideband cognitive radio system
  • Crosslayer design and optimization
• Intelligence and learning capability:
  • Cognitive machine learning techniques
  • Game theory for dynamic spectrum access
  • Genetic and artificial intelligence-inspired algorithms
• Implementation:
  • Architectures and building blocks of dynamic spectrum access
  • Combined architectures for SDR and dynamic spectrum access
  • Wideband or multichannel transmitter design and spectrum sensing
  • Bandpass sampling receivers
  • Landau-Nyquist sampling receivers
  • Digital compensation of RF imperfections
