| 摘 要： | 现有的OFDMA资源分配算法大都以提高单系统内的频谱利用率为目标,而对于同一区域内多系统间的资源共享问题未加考虑.针对这一问题提出了一种适用于双无线系统的半静态的资源分配策略.首先划分一定的频谱共享区并设置系统间的优先级,然后引入一种泊松评判机制来控制不同系统接入频谱共享区的概率,从而降低系统间的互干扰.结合几种分配算...

| Abstract: | Most of the current OFDMA resource allocation algorithms targets on the spectrum utilization improvement in single system without considering the resource sharing for multi-system in the same area.To deal with this problem,a semi-static resource allocation strategy is proposed applicable to dual wireless system.First of all,a sharing spectrum region is chosen with the priority between systems being set.Then a Poisson evaluation mechanism is introduced to control the probability of accessing the spectrum sha... |
