Confidential communications technique based on message block precoder in multi-user MIMO systems

For confidential communications in a multi-user MIMO wiretap channel, though no information regarding the illegitimate receiver was presumed at the transmitter, an artificial interference and a precoding technique based on message block were proposed. Except for confidentiality, the effectivity and...
