Resource Allocation for Multiuser MIMO-OFDM System Based on Proportional Fairness
Author(s): 
Pages: 62-65
Year: Issue:  9
Journal: Video Engineering

Abstract: 提出了一种基于比例公平原则提高MIMO-OFDM系统吞吐量的子载波和功率分配算法.它在总功率和误比特率的约束下,以获取最大系统吞吐量为目标,同时为兼顾用户间资源享用的公平性,根据用户速率成比例推导出了子载波分配限制准则.仿真结果表明,本算法不仅可满足不同用户的速率要求,而且平衡了容量最大化和用户间公平性的矛盾,同时计算复杂度较低.
