Secrecy capacity analysis of MISO system with artificial noise

Adding artificial noise in the MISO system was an effective method to improve the security.The transmit power allocation and artificial noise generation was mainly discussed.An artificial noise model of MISO system was presented,in which the artificial noise was regarded as additive channel noise.It...

description Adding artificial noise in the MISO system was an effective method to improve the security.The transmit power allocation and artificial noise generation was mainly discussed.An artificial noise model of MISO system was presented,in which the artificial noise was regarded as additive channel noise.It was proven that when the artificial noise was distributed on Gaussian distribution,the secrecy capacity of MISO system was maximized,and the expression of this secrecy capacity was deduced.Considering the transmit power constraint and using the vector space projection method,The optimum power allocation is obtained.Given a power allocation,the artificial noise is generated by Box-Muller transformation,which was distributed on Gaussian distribution.And with the vector projection method,the artificial noise meets the optimum power allocation.
