摘要
针对多用户协同通信系统中的剩余功率分配不合理问题,提出了一种基于用户间公平性的子载波分配和优化剩余功率分配的联合资源管理算法.首先在保证用户资源分配公平性下给出基于平均功率分配下的子载波分配,其次利用调和平均值算法对剩余功率进行优化分配.仿真结果表明,所提出的算法能够在满足用户质量需求和公平性的同时,可提高系统的容量和用户容量,降低系统的误码率.
For the unreasonable problem of power allocation in multi-user cooperative communication system, the joint resource management algorithm of subcarrier allocation and optimizing the remaining power allocation was put forward based on the user fairness. First under the guarantee of user resource allocation fairness, sub- carrier allocation based on the average power allocation was given, then optimizing the surplus power allocation by the harmonic mean algorithm. The simulation results show that the proposed algorithm can both meet the quality requirements and user fairness, further the capacity of the system and the user capacity were improved, the error rate of the system was reduced.
