Mobile equipment position control method and device for dynamic noise based on signal-to-interference and noise ratio

Abstract

The invention provides a mobile equipment position control method and device for dynamic noise based on signal-to-interference and noise ratio, and the method comprises the steps: determining a first change trend of a first secrecy capacity of a communication system in an (n+1)-th time slot relative to a second secrecy capacity of the communication system in an n-th time slot; determining a first change trend of a first interception capacity of mobile equipment in an (n+1)-th time slot relative to a second interception capacity of the mobile equipment in an n-th time slot; determining the SINR of a signal received by the mobile equipment in the same time period; adjusting the transmission power of target end equipment in transmitting a manual noise signal; and transmitting the feedback information to the mobile terminal according to the first change trend. According to the embodiment of the invention, the method can achieve the control of the movement position of the mobile equipment according to the feedback information, achieves the further optimization of the secrecy capacity of the communication system through the adaptive adjustment of the manual noise signal, and enables the safe communication to be carried out continuously.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for controlling the position of mobile equipment based on dynamic noise of signal-to-interference-noise ratio. Background technique [0002] With the convenience brought by wireless communication, people will use wireless networks extensively for sensitive and private information transmission in daily life. Traditional wireless networks ensure the security of information through high-level encryption technology, which assumes that the computing power of the eavesdropping end (ie, mobile device) is limited. However, with the rapid development of distributed computing and the continuous improvement of computing power at the eavesdropping end, this assumption has become increasingly unreliable. The physical layer security technology has received more and more attention. It uses the legitimate target device to have better signal reception quality (...
