Abstract

The invention provides a mobile device position control method and a device based on single bit 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 useful signals and the artificial noise signals are processed to acquire processed signals, and the processed signals are sent to the target-end device; feedback information returned for the processed signals by the target-end device is received, wherein the feedback information is used to indicate whether the secrecy capacity of the communication system is promoted simultaneously with the eavesdropping capacity of the mobile device; and according to the feedback information, a moving position is determined, and the current position of the mobile device is moved to the moving position. The embodiment of the invention can control the moving position of the mobile device, the secrecy capacity of the communication system is further optimized, and safety communication is ensured to be lasted.

Description

Technical field [0001] The present invention relates to the technical field of communication equipment, and in particular to a position control method and device of mobile equipment based on single-bit feedback. Background technique [0002] With the convenience brought by wireless communication, people will use wireless networks to transmit sensitive and private information in daily life. Traditional wireless networks use high-level encryption technology to ensure information security, which assumes that the computing power of the eavesdropper (ie, mobile device) is limited. However, with the rapid development of distributed computing and the continuous improvement of the computing power of the eavesdropping terminal, this assumption has become increasingly unreliable. The physical layer security technology has received more and more attention. It uses the legal target device to have better signal reception quality (such as signal-to-noise ratio) than the eavesdropping device t...
