Weighted Sum Rate Optimization for Cognitive Radio MIMO Broadcast Channels
In this paper, we consider a cognitive radio (CR) network in which the unlicensed (secondary) users are allowed to concurrently access the spectrum allocated to the licensed (prim...

Optimal Power Allocation for Cognitive Radio Under Primary User's Outage Loss Constraint
In this paper, we consider a secondary link sharing the spectrum with a primary link in a fading cognitive radio (CR) network. Instead of applying the conventional interference pow...

Opportunistic channel access scheme for cognitive radio system based on residual white space distribution
We propose an opportunistic channel access scheme for cognitive radio-enabled secondary networks. In our work, we model the channel occupancy due to Primary User (PU) activity as a...
