基于混合业务的OFDMA系统资源分配
Resource allocation in OFDMA systems based on heterogeneous services
摘要
Abstract
Aiming at the subcarrier and power allocations in orthogonal frequency division multiple access（OFDMA） system with heterogeneous services,a suboptimal resource allocation algorithm based on a tradeoff factor was proposed.Under the limitation of total transmitting power,the proposed algorithm could not only maximize the throughput of the system,but also ensure the QoS requirements from real time users and the proportional fairness of resource allocation among non real-time users.The adaptive resource allocation and adaptive modulation were combined in the proposed algorithm,and the bit adjustment and optimization processing were introduced in the algorithm.An efficient tradeoff for the resource usage between both real-time and non real-time users was performed.The analysis and simulation results show that without increasing the complexity,the SRATF algorithm can reduce the running time,and guarantee the fairness between non real-time users.关键词
