Spectrum Sharing and Sensing for Future Broadband Networks: The Cognitive Radio Technology

Description

A recent measurement campaign on spectrum utilization promoted by the Federal Communication Commission throughout the US has revealed that significant portions of the electromagnetic spectrum are rarely exploited for considerable intervals of time, thus paving the way to a number of possibilities for increasing bandwidth utilization among multiple users in shared radio networks. The clue to improve spectrum utilization, as well as efficiency, comes from communications systems exploiting the so-called Cognitive Radio technology, which at the physical layer, as well as at upper-levels of the network, can adaptively and dynamically allow users to access radio resources by switching among portions of unused bandwidth in different intervals of time.

The cognitive radio technology is still in its infancy, and many problems at a theoretical, as well as practical, level have to be solved before this technology may be fully exploited in next generation wireless networks.

The main aim of this special issue is to highlight state-of-the-art techniques on the most recent research advances in cognitive radio networks.

Topics of interests include, but are not limited to, the following subject categories:

  • Advanced algorithms on coding and modulation for software radio and cognitive radio networks
  • Cross-layer algorithms based on spectrum sensing techniques
  • Distributed algorithms for spectrum detection
  • Information theory and performance limits of dynamic spectrum access
  • Multimedia communications through cognitive networks
  • Physical-layer design of software radio and cognitive radio transceivers
  • Resource allocation for spectrum sharing in cognitive networks
  • Spectrum management in cognitive radio networks
  • Reconfigurable low-complexity transceiver architectures for channel adaptation in cognitive radio networks
  • Radio test beds
  • Regulatory policies on spectrum sharing for future broadband networks
