Abstract
A system and method for probability-based resource allocation in a wireless communications system is provided. A method for centralized resource allocation includes coordinating spectrum sensing information with a set of cognitive radio (CR) user pairs, computing probability-based information for CR user pairs in the set of CR user pairs, computing adjustment values for each channel available for allocation, assigning a CR user pair to an unassigned channel in a set of channels available for allocation, the assigning based on the probability-based information, updating the adjustment values, repeating the assigning a CR user pair and the updating the adjustment values if the adjustment values have not converged, and transmitting a message to the set of CR user pairs, wherein the message comprises information regarding CR user pair to channel assignments.
