A paper entitled 'Competing Cognitive Tactical Networks' which was published in issue 20 of the Lincoln Laboratory Journal in 2014 written by Siamak Dastangoo, Carl Fossa and Young june Gwon stated that: "The capability of radios to dynamically search for, learn and access available spectrum resources can greatly improve performance in a congested environment." Rohde and Schwarz' statement continued that: "By acquiring awareness about the current radio environment and the other spectrum users,
cognitive radios can more efficiently exploit idle spectrum and manage interference."
(14) to determine the estimated number of channels to be finely sensed by the
cognitive radio, where the most conservative modulation scheme (i.e., BPSK) is assumed in the transmission.
In a number of earlier publications
cognitive radio was envisioned as self-reconfiguring SDR.
The scenario considered is as follows: a
cognitive radio network is considered which has one PU, some SUs, and MSUs.
