摘　　要：传统的扩频载波通信路由搜索算法运行效率低,运行过程所需的存储空间较大。针对上述问题,在中断频率分析下研究了一种新的扩频载波通信路由搜索算法,利用有向图表示扩频载波通信网络,构建网络模型,通过迭代操作,提高容错性,确定发送节点、中继节点、转发节点的位置后,构建信号模型,同时分析干扰位置,建立干扰模型。利用得到接收端最远蜂窝终端的上行链路资源,判定扩频载波通信路由的中断概率门限值,分别搜索最佳中继节点和最佳转发节点,通过协作方式向最佳转发节点传递数据信息,直到获取想要搜索的目的节点为止。实验结果表明,提出的搜索算法搜索效率、运行过程所需的存储空间等方面都优于同类算法。The traditional spread⁃spectrum carrier communication routing search algorithm has low operating efficiency and requires a large amount of storage space during operation.Aiming at the above problems,a new spread⁃spectrum carrier communication routing search algorithm is studied under the analysis of interruption frequency.The directed graph is used to represent the spread⁃spectrum carrier communication network,and a network model is constructed.Through iterative operations,fault tolerance is improved,and the sending node after the relay node is the position of the relay node,a signal model is constructed,and the interference position is analyzed to establish an interference model.Use the uplink resources of the farthest cellular terminal at the receiving end to determine the threshold of the probability of interruption of the spread spectrum carrier communication route,search for the best relay node and the best forwarding node,and pass data to the best forwarding node in a cooperative manner information until you get the destination node you want to search.Experimental results show that the proposed search algorithm is superior to similar algorithms in terms of search efficiency and storage space required during operation.
