  • A cross-layer scheduling algorithm for downlink of multi-user OFDM system is proposed, the algorithm considers users QoS requirement, fairness, packet queue state information of MAC layer and channel state information, power constraint of physical layer. Multi-user OFDM system can make efficient use of different parameter characters of the both layers through the proposed algorithm, to achieve the goal of guarantee users QoS and maximize wireless resource utility efficiency. Simulation results show that when mobile users have different receive SNR, the proposed algorithm has steady QoS, low drop rate and low complexity.
