Abstract
Wireless networks are evolving toward networks of small, smart devices that opportunistically share the wireless spectrum with minimal infrastructure and coordination. The new generation of smart terminals can provide intelligent adaptive services by adjusting to the environment thanks to the software-defined radio (SDR) technology. This intelligence is incorporated into a cognitive cycle,1 which allows the wireless device to gather information about its environment (“learn”) and make decisions (“act”) regarding its transmission parameters and possible access strategies. The development of this new technology is further motivated by the new paradigm of the FCC’s spectrum management policy2 that has adopted new rules to promote active spectrum sharing techniques in both licensed and unlicensed bands.
