Integration of Signal and Artificial Noise in MIMO Wiretap Channel
Abstract: In this paper, the
integrated signal-to-artificial noise (ISAN) design is applied in MIMO wiretap channel
to ensure wireless communication security. When the information of eavesdropper
is unknown,the total power is divided into two parts: signal and artificial
noise. The signal can secure certain quality at the legitimate receiver. The
artificial noise which is in the null space of the receiver channel matrix can deteriorate
eavesdropper channel by the method of beam forming. The artificial noise power
is distributedevenly in other space, so that the eavesdropper channel is
deteriorated in all directions. The signal tointerface and noise ratio (SINR)
is regarded as the efficient parameter on measuring reliability and security of
information at the legitimate receiver. The simulations reveal that ISAN can
deteriorate the eavesdropper channel and safeguard the information transmission
on the premise of the given SINR of the legitimate receiver.
