An existing ns-2 network simulator was extended to support cognitive radio
network simulation in .
Li's work promises to significantly advance spectrum sensing for cognitive radio
in vehicular applications.
Eighteen parameters have been identified which have critical influence on the QoS of a cognitive radio
Several secondary users are randomly distributed in the cognitive radio
Alghamdi  proposed a new method to optimize the overall performance in hard cooperative spectrum sensing in cognitive radio
The adoption of cognitive radio
technologies, like xMax, could lead to a dramatic increase in spectrum efficiency, which would help ensure that consumer, commercial and government users of wireless systems will maintain unobstructed wireless connectivity in the face of skyrocketing demand.
Spectrum management business processes will harness these two forces to put cognitive radio
systems and software defined radios into the hands of warfighters.
CH being itself a cognitive radio
also sense spectrum and then combine the overall information in a way to obtain the list of legitimate available frequency holes (Coile, 1997).
Por su parte, el SDR Forum Special Interest Group for Cognitive Radio
, el cual se centra en el desarrollo de aplicaciones para Cognitive Radio
, lo define como:
Where spectrum is used on an exclusive basis, parties could negotiate ways to access frequencies any time a cognitive radio
technology (deployed, for instance, in the radio systems of the lessee) senses white spaces available for transmissions.
Under the terms of the agreement InterDigital will sponsor and help guide research on cognitive radio
models for wireless systems.
These two new patents, along with the existing eight patents we have already received for spectrum sharing, cognitive radio
and interference mitigation technology, reinforce our leadership position in helping the wireless industry as it addresses the mounting spectrum crunch's future impact on consumers and business," said Thomas Stroup, SSC's CEO.
