Resource assignments algorithm based on energy efficiency optimization in OFDM relay networks

In cooperative orthogonal frequency division multiplexing (OFDM) systems, the resource allocation rationally is significant to enhance the system performance. Aiming at maximizing the total system energy efficiency, the joint assignment problem of relay, sub-carrier and power among users is modeled....
