Abstract
In multicast orthogonal frequency division multiplexing (OFDM) systems the varieties in link conditions of users decreases the throughput of users. If we assign the subcarriers which are in the best channel condition among all the subcarriers for multicast users in the base station, the network throughput can be increased by performing subcarrier allocation. In this paper, we propose a joint cross-layer and adaptive subcarrier allocation algorithm for multicast OFDM systems. This algorithm takes into consideration the physical channel condition in both physical layer and MAC layer. In MAC layer we use packet scheduling algorithm. Simulation results show that with increasing the number of users or bandwidth demanded, this joint algorithm enhances the system performance and increases throughput of multicast users besides decreasing packet loss in the channel
