Abstract

Abstract

A sub-optimal resource allocation algorithm for broadcast/multicast OFDM system is presented in this paper. By proposed algorithm, the fairness and efficiency is improved based on taking the target rates of different services as Quality of Service (QoS) constraint and finding out the lowest rate in one service group for comparison in order that all users can get target QoS requirement. At the same time, the complexity of this algorithm is reduced by introduction of two-dimensional Frequency-Time Grid (FTG) scheme. Simulation results show that the efficiency of proposed allocation algorithm is obvious which has significant higher fairness and throughput being very close to the upper bound of optimum method.
