Dynamic Spectrum Access: Implications of the diffusion of spectrum sharing technology.
, 2012 Like most common natural resources, spectrum is finite and prone to overuse and "crowding". Most of today's radio systems are not aware of the spectrum environment and operate in a pre-given, static frequency band. Technologies such as cognitive radio (CR) that enable dynamic spectrum access (DSA) have been proposed to improve efficiency and ...
