Multicarrier communication techniques for spectrum sensing and communication in cognitive radios

  title={Multicarrier communication techniques for spectrum sensing and communication in cognitive radios},
  author={Behrouz Farhang-Boroujeny and Roland Kempter},
  journal={IEEE Communications Magazine},
In this tutorial article we review different multicarrier communication methods for the physical layer of cognitive radio systems. There, secondary users need to dynamically and reliably determine spectral holes, and transmit data in these resources without interfering with other parts of the frequency band. To satisfy the first, each SU has to be equipped with a spectrum analyzer. To satisfy the second, it is widely accepted that a multicarrier modulation technique should be adopted. Moreover… CONTINUE READING
