摘　　要：在集合PC机、无线传感器和Wi-Fi等通信网络进行无线传输网络组网中,功率消耗大,路径损耗多,需要进行无线传输网络组网交叉覆盖,以提高网络的吞吐性和抗干扰性。提出一种基于被动相干盲源分离算法的改进大功率无线传输网络组网交叉覆盖算法,构建大功率交叉网络模型,得到大功率交叉网络树状拓扑结构。采用隶属度调度控制Hough原理,对大功率交叉网络的分层信息数据进行分段处理,求解路由节点周期性的在一跳范围的检验统计量,在交叉网络跨层信息共享中,通过删除缓存数据得到跨层信息分组,实现交叉覆盖,实现无线传输网络组网交叉覆盖算法改进。通过仿真实验进行性能验证,得出采用该算法进行无线传输网络组网交叉覆盖,能改善输出信号质量,提高网络传输吞吐量,降低功耗损失。In wireless transmission network collection of PC machine, wireless sensor and Wi-Fi communication network,large power consumption, path loss, the need for wireless transmission network cross coverage, to improve the network throughput and anti-jamming. Proposes an improved power wireless transmission network passive coherent blind source separation algorithm based on cross covering algorithm, the construction of large power cross network model, high power cross tree topology network. The membership of dispatch and control principle of Hough, the hierarchical data of high power of cross network segment treatment, solving the routing nodes periodically in one hop range of test statistics, cross layer information sharing in the cross network, delete cache data obtained through cross layer information packet, the realization of cross coverage,the realization of wireless transmission network cross cover algorithm improvement. The performance is verified through simulation experiment, obtained by the algorithm of wireless transmission network cross cover, it can improve the quality of output signal, and improve the network throughput, reduce power loss.
