Cognitive Radio Technologies:
Services and Software for Intelligent Wireless Networks

A cognitive radio incorporates advanced signal processing
techniques to intelligently leverage situational knowledge
and previous experience to improve the performance of
existing applications (e.g., reliability, throughput, latency)
and to enable new applications (e.g., dynamic spectrum
access, spectrum trading, automated network management)
Realizing these performance gains and new applications requires the use of
numerous techniques not typically encountered in traditional wireless systems.
CRT has been at the forefront of developing these techniques and can help bring
your engineers up to speed with a 1-day or 2-day tutorial on critical aspects of
cognitive radio and modern radio engineering including:
  • Signal detection and classification (cyclostationarity analysis, hidden
    Markov models, neural networks)
  • Decision processes (genetic algorithms)
  • Networking issues (decision coordination, game theory)
  • Regulatory issues (700 MHz, 3.65 GHz)
  • Languages (etiquettes, ontologies)
  • Likely research directions
  • Applications (dynamic spectrum access, automated bridging, cooperative
  • Emerging cognitive radio standards such as 802.22, 802.16h, 802.11y and
    IEEE 1900

Recognizing that different companies have different backgrounds, we tailor each
tutorial to the specific needs of each customer. For example, the outline and
selected slides from our 1 day tutorial at GDC4S in April 2007 is available below.

Past public tutorials on cognitive radio include our tutorial @ DySPAN 2005 and at
the Wireless @ Virginia Tech Summer Schools.  

More information about the tutorials and engineering services offered by CRT is
