Secrecy performance analysis of TAS/MRC system in the presence of channel estimation error

This paper presents secure transmission in transmit antenna selection with maximal ratio combining (TAS/MRC) over Rayleigh fading channel for multiple input multiple output (MIMO) taking channel estimation error into account. In this paper, we evaluate the probability of non-zero secrecy capacity (PNZSC) and secrecy outage probability (SOP) for TAS/MRC system considering the impact of channel estimation error (CEE). The numerical results show that the system is valid for any transreceiving and eavesdropping antennas in general.
