| 摘 要： | 基于自适应OFDMA系统,对多业务系统中基于总发射功率最小化的无线资源管理问题进行研究,并使用着色Petri网(CPN,coloured Petri nets)以及CPN分析工具CPN Tools对其进行建模。采用Monitor监控器对模型进行仿真分析,并将仿真结果与随机Petri网(SPN,stochastic Petri nets)模型以及基于吞吐量最大化的CPN模型进行比较,验证了该系统模型的正确性和优越性。

| Abstract: | The problem of the Radio Resources Management plays an important part in OFDMA system.By using CPN(colored Petri nets)methods and CPN Tools,a hierarchical model of adaptive OFDMA system using the MA(Margin Adaptive) algorithm is established.In order to estimate the performance of system,Monitors are introduced to collect datas for the following analysis.The seperate comparisons between the proposed model and two different models: the SPN(stochastic Petri nets) model and the CPN model using RA(Rate Adaptive) algorithm,shows great validity and superiority of this model. |
