Physical layer security of MIMO STBC over Rayleigh fading channels in the presence of channel estimation error

This paper presents secure transmission in orthogonal space time block codes (OSTBC) in the presence of channel estimation error over multiple input multiple output (MIMO) wiretap channels. In this paper, we evaluate probability of non-zero secrecy capacity (PNZSC) and secrecy outage probability (SOP) for OSTBC system over Rayleigh fading channels considering the impact of channel estimation error (CEE). The numerical result demonstrates that the system is generic and valid for any transceiving and eavesdropper antennas.
