Title:
DISTRIBUTED SECURE BEAMFORMING METHOD AND APPARATUS BASED ON FEEDBACK CONTROL
Document Type and Number:
WIPO Patent Application WO/2019/006715
Kind Code:
A1
Abstract:
The present invention provides a distributed secure beamforming method and apparatus based on feedback control. The method comprises: receiving feedback signals sent by a receiving end device, the feedback signals being used for indicating whether a first signal to interference plus noise ratio (SINR) of the receiving end device on a nth timeslot is enhanced relative to a second SINR stored by the receiving end device on the nth timeslot; and adjusting, according to the feedback signals, relevant parameters of a transmission weight of first artificial noise signals sent on a (n+1)th timeslot, the relevant parameters comprising a transmission phase, a correction factor and a random disturbance. By means of embodiments of the present invention, distributed secure communication can be implemented, and the secrecy performance of a distributed secure communication system is improved.
