Abstract

Security is an important issue in the field of wireless communication. In this paper, the security problem of Multiple-inputs Single-output (MISO) wireless channel is considered. To ensure the security of communication, the transmitter utilizes some of the available power to produce ´artificial noise´ that only degrades the eavesdropper´s channel. But the artificial noise may be invalid possibly due to the inherent security weakness. We research the vulnerability of the MISO wireless channel with artificial noise (MISOAN) through vector analysis. Then a Blind Space Elimination (BSE) scheme is proposed and proved to fix the design flaw in order to strengthen the original one.
