摘要
MF-TDMA因其灵活的分配策略和信道利用率在通信系统中广泛使用。由于信道资源有限性以及用户需求的多变性,使得如何将有限的信道最大的利用以便为更多的用户服务成为MF-TDMA的关键问题。针对这一问题,文章首先对MF-TDMA信道结构进行处理,将MF-TDMA的信道分配问题转为二维装箱问题。然后,针对该问题的常规算法FFA进行改进,提出了基于最小资源浪费率的FFA贪心算法(IFFA)。最后,对给出的结果进行了简单的验证。
MF-TDMA is used widely in lots of commution systems because of its bandwidth efficiecy and agile channel-allocated strategy.Because the channel resource is limited and the user need is mulriple,how to increase the utilization of the channel to server more users become the key problem of MF-TDMA.In this paper,the channel struct of MF-TDMA is analysed first,then a better algorithm named improved FFA greedy algorithm based on lease waste is offered.And finally,the performance of the algorithm is evaluated.
