Cognitive radio: brain-empowered wireless communications

  title={Cognitive radio: brain-empowered wireless communications},
  author={Simon Haykin},

Cognitive radio is viewed as a novel approach for improving the utilization of a precious natural resource: the radio electromagnetic spectrum. The cognitive radio, built on a software-defined radio, is defined as an intelligent wireless communication system that is aware of its environment and uses the methodology of understanding-by-building to learn from the environment and adapt to statistical variations in the input stimuli, with two primary objectives in mind: /spl middot/ highly reliable… CONTINUE READING
