Problems solved by technology

In the existing jamming technology based on the power domain, the focus is often on the game between the legal jammer and the illegal user, ignoring the power leakage of the legal jammer to the same-frequency users (considering limited spectrum resources) The influence of legal jammers increases the transmission power, which will not only cause greater interference to illegal users, but also bring losses to their own users

Embodiment Construction

[0062] In the case of tight spectrum resources, in order to solve the problem of legal parties meeting their own basic communication needs and maximizing the suppression of illegal user activities, such as figure 1 and figure 2 As shown, the present invention proposes a method. The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] (1) Model the communication scenario of the game of transmission power between the legal jammer and the illegal user as a jamming counter-Stackelberg Steinberg game, define the utility function of both parties in the game, and set the legal jammer and the illegal user as the leader and follower respectively By;

[0064] (2) According to the action of the jammer, the illegal user finds out the best response strategy;

[0065] (3) Based on the best countermeasures of illegal users, the jammer analyzes and plans its own optimal jamming strategy while meeting the basic ...

Abstract

The invention provides a communication power control method based on an interference countering game. According to the method, modeling processing is carried out on a communication scene of a legal jammer and illegal user transmitting power game; the method comprises the following steps: 1) modeling a communication scene as an interference countering Steinberg game, constructing a utility functionof a legal jammer and an illegal user, and supposing that the legal jammer and the illegal user are respectively used as a leader (the jammer senses that the illegal user firstly acts) and a follower; 2) solving an optimal coping strategy by an illegal user according to the action of the jammer; and 3) analyzing and planning the optimal jamming strategy of the legal jammer by the legal jammer based on the optimal coping strategy of the illegal user while meeting the basic communication requirements of the legal user. According to the method, the activity of illegal users can be inhibited to the maximum extent under the condition of meeting the basic communication requirement of the own side in an environment with tense spectrum resources. The method accords with a real communication scene, and achieves the organic combination of optimal interference and defense assistance.

Description

technical field [0001] The invention relates to the field of communication game confrontation, in particular to a communication power control method based on interference counter game. Background technique [0002] Activities of illegal users (such as stealing secrets, malicious interference, etc.) will pose a threat to the communication security of legitimate users, especially if the geographical location of the two parties is relatively close, the degree of harm will increase. In the existing jamming technology based on the power domain, it is often only concerned with the game between the legal jammer and the illegal user, ignoring the power leakage of the legal jammer to the same-frequency users (considering limited spectrum resources) The influence of legal jammers increases the transmission power, which will cause greater interference to illegal users and also bring losses to their own users. Therefore, considering the existence of legitimate users on one's own side i...
