%X User requirement is not considered in existing spectrum allocation algorithms for the cognitive radio,which results in excessive allocation of resources to users with less demand.To solve the above problem,two spectrum allocation algorithms,which included spectrum allocation algorithm based on user requirement and joint proportional fairness algorithm,were proposed.They both consider user requirement as the needed factor of spectrum allocation.Numerical results indicate that these two algorithms are better ...
