- W2378996445 abstract "Adaptive resource allocation for multicast OFDM system is studied in this paper. The objective is to maximize the spectrum efficiency while guaranteeing the BER requirement of each multicast service. Considering the discrete modulation orders in practical systems,we first extend the resource allocation algorithm with continuous bits to discrete bit cases,which results in performance loss. To improve the system performance,a multiple description coding based resource allocation algorithm is proposed. The decoding flexibility of multiple description coding is well exploited,and the resource allocation is performed more effectively. Simulation results show that the proposed algorithm can improve the system performance under different scenarios." @default.
