A design method of failure network node communication performance evaluation system based on VXI bus interactive dynamic configuration is proposed to construct wireless network entity object model and describe the overall design of the communication system. The fractionally- spaced equalization matching filtering detection method is used for detection design of network failure node to improve the anti- jamming performance of networks. On this basis, the circuit for localization module of the nodes in failure network was de- signed, and the communication performance evaluation of nodes in the failure network was realized. The experimental results show that the method can realize communication performance evaluation of the nodes in failure network, improve the network anti- jamming performance, throughput of network data transmission and security Of networks, and reduce the hit error rate of node communication.
