Cognitive
Radio can be programmed & configured dynamically to use the most effective
wireless channels in its vicinity to avoid user interference. The CR is capable
of altering parameters like “waveform, protocol, operating frequency, etc.”.
The CR functions as an autonomous system in the communication environment,
while exchanging information in its cognitive network with other cognitive
radios. This paper discusses how to improve the spectrum utilization & how
spectrum holes in space-time frequency multiple dimensions should be exploited
accurately & efficiently.
