Method for maximizing monitoring non-interrupting probability of system

Abstract

The invention relates to a method for maximizing monitoring non-interrupting probability of a system. The method comprises steps, 1) a legal monitoring node estimates signal channel state information in a communication system through monitoring pilot frequencies of a suspicious emitting node and a suspicious receiving node; 2) the legal monitoring node calculates the best emitting power pd and emission, the emitting and receiving beam forming devices wt and wr on the basis of the maximized system monitoring non-interrupting probability by using the signal channel state information estimated; 3) when the suspicious emitting node is in communication with the suspicious receiving node, the legal monitoring node can maximize the monitoring non-interrupting probability of the system under the full dual-working mode on the basis of the best emitting power pd and the emitting and receiving beam forming devices wt and wr. The method can make the disturbing signal generate big disturbance to the suspicious receiving node while slightly impact on the legal monitoring node, thereby largely promoting the monitoring non-interrupting probability of the whole communication system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for maximizing the non-interruption probability of system monitoring. Background technique [0002] With the progress of society and the development of science and technology, wireless communication technology is constantly improving and improving people's life style and quality. As a core issue of wireless communication, network security has always been the focus of people's attention, and it is also the condition for the large-scale popularization and application of wireless networks. In order to meet the challenge of secure transmission in wireless communication network, wireless communication physical layer security technology emerges as the times require, and has become a current research hotspot. Starting from the perspective of information theory, physical layer security technology uses the uniqueness and reciprocity of physical channels to implement information encrypt...
