In the process of multiterminal power communication,due to the poor interconnection of the links of the power communication system,the antiinterference ability of the communication network is low.In order to solve this problem,the antiinterference method of the multiterminal power communication network based on the ubiquitous Internet of things was proposed.The ubiquitous Internet of things was used to connect the power communication network,connect the communication network with the network layer,obtain the information of the communication network,extract the vector of power communication network channel transmission,and conduct channel prediction and transmission channel division.The signal model of multiterminal power communication network was established,the linear timevarying signal in the power communication network was obtained,and the signal power was expanded to obtain the antiinterference model of multiterminal power communication network,so as to complete the interference suppression of multiterminal power communication network.The experimental results show that the designed method has strong antiinterference ability,good interconnection of power communication system,and can meet the antiinterference requirements of multiterminal power communication network.Thus it has certain practical application significance.
