| 摘 要： | 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...

| Abstract: | A subcarrier and power allocation algorithm based on proportional fairness is proposed to achieve high total transmission rate in multiuser MIMO-OFDM systems.Subject to constraints on total power bit error rate the algorithm can maximize overall data throughput while guaranteeing the proportional fairness among users and the criteria of subcarrier allocation is derived based on each user rate proportionality constraints.The simulation results show that the algorithm can satisfy differently required data rat... |
