In this paper the authors investigated the adaptive modulation strategies for Multicast service in orthogonal frequency division multiple access systems. They defined a Reward function as the performance optimization target and developed adaptive modulation strategies to maximize this Reward function. The proposed optimization algorithm varied the instantaneous BER constraint of each mobile Multicast receiver according to its individual cumulated BER, which resulted in a significant Reward gain. The next generation mobile cellular networks are expected to transmit rich multi-media services, e.g, live video/audio streaming, online mobile gaming, music download, etc. Many of these services require large transmission bandwidth and the same content needs to be delivered to several users.
