OFDMA系统中基于QoS的资源分配算法
Resource Allocation Algorithm Based on QoS in OFDMA System
摘要
Abstract
Aiming at the multi-user diversity characteristic of Orthogonal Frequency Division Modulation(OFDMA) system, an adaptive resource allocation algorithm based on Quality of Service(QoS) is proposed. The algorithm adopts simple equal power distribution because of the multiuser-diversity and the Adapt Modulation Coding(AMC), so the algorithm complexity is distinctly reduced. Simulation results indicate that the proposed algorithm has better system performance on users QoS satisfaction and user fairness although it sacrifices a little system throughput.关键词
