Trusted Communication Technique in Single-user MIMO System
Yao Zhu, Pla Information · Communications technology · 2011
The artificial interference on trusted communications in a single MIMO wiretap channel with a single transmitter,a single legitimate receiver,and a single illegitimate receiver is studied.No information for unknown illegitimate receiver is presumed at the transmitter,Two methods for the design of artificial interference and the effective precoding algorithm are proposed.This algorithm could improve the transmission direction and maximizes the influence of artificial interference on the illegitimate receiver.The simulation results shows that the artificial interference by this precoding algorithm could greatly reduce SINR of the illegitimate receiver,while satisfy the demand of the lowest SINR for the legitimate receiver.
