Abstract

The invention provides a mobile device position control method and a device based on adaptive noise feedback. The method comprises steps: useful signals sent by a source-end device and artificial noise signals sent by a target-end device are received at the same time; the signal to interference and noise ratio (SINR) of the signals received by the mobile device is determined; and according to the SINR, a moving position is determined, and the current position of the mobile device is moved to the moving position. According to the embodiment of the invention, the moving position of the mobile device can be determined according to the SINR, the secrecy capacity of the communication system is further optimized through adaptively adjusting the power of the artificial noise, and safety communication is ensured to be lasted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a position control method and device of a mobile device with adaptive noise feedback. 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 (such as signal-to-noise ratio) than the eaves...
