Joint rate and power allocation for cognitive radios in dynamic spectrum access environment
Abstract--We investigate the dynamic spectrum sharing problem among primary and secondary users in a cognitive radio network. We consider the scenario where primary users exhibit o...

Identifying boundaries of dominant regions dictating spectrum sharing opportunities for large secondary networks
An important parameter in determining a spectrum sharing opportunity is the level of interference power that secondary users may generate towards primary users. It is indicated in ...
