| 摘 要： | 分析了后三代(B3G)移动通信系统中无线链路的传输模型和所承载各种业务的QoS需求,提出一种可以提高系统性能的混合式无线资源管理方法.采用此方法设计出适用于多输入多输出(MIMO)无线信道和流媒体业务QoS要求的联合无线资源调度和功率分配的算法(JASPD算法).计算机仿真结果表明, 与传统的无线资源管理算法相比,JASPD算法能够在相同复杂度条件下使得系统容量平均提高10%,同时将业务的丢包率平均减少32%.

| Abstract: | A hybrid radio resource management (RRM) method, which is based on the analysis of wireless link transmission model and quality of service (QoS) requirements of different services, is proposed to beyond 3G mobile communications sy stem. A joint algorithm of scheduling and power distribution (JASPD) algorithm applicable to multiple-input multiple-output (MIMO) mobile communications system with streaming media service is then deduced from the hybrid RRM method. Simulation results d emonstrate that JASPD algorithm can bring the average system-capacity increment o f 10% and packet-discarding-ratio decrement of 32% with the same complexity. |
