The primary feature of cognitive radios for wireless communication systems is the capability to optimize the relevant communication parameters given a dynamic wireless channel env...
- Current wireless systems are called vendor-central systems because, users should subscribe to a service provider (vendor) and receive the service through the spectrum assigned to...
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...
