This paper proposes the joint optimization of power allocation, subcarrier assignment and relay selection strategy for cooperative OFDM system to maximize the total capacity. We use Lagrangeandual approach for relaxing some available constraints and also make use of the simple greedy algorithm to perform lesser iterations to converge. Extensive experiments with realistic data prove that the subgradient dual method is approriate to dynamic resource allocation.
