Abstract
- This paper presents the secrecy performance of a user and antenna selection at transmitter (i.e., combined scheme) over channel estimation inaccuracy in wiretap channels with multiple antennas. This paper develops the precise formulations of the combined system for the secrecy outage probability and the probability of the non-zero secrecy capacity. This work develops the diversity order for the secrecy outage probability in the presence and absence of channel inaccuracy at the combined system and eavesdropper. This work provides various numerical evaluations, showing that, the diversity order of the combined system is changed only by combined system‘s channel inaccuracy not by eavesdropper's channel inaccuracy. Also, the channel inaccuracy of the eavesdropper acts on the signal to noise ratio (SNR) gain of the combined system. [ABSTRACT FROM AUTHOR]
