“…For the situation where the receiver and the eavesdropper show Gaussian errors at the same time, Shrestha and Kwark (2014) and Hu and Tao (2015) extended the work of Gans (1971) and Tomiuk et al (1999), and studied the secrecy outage probability in SIMO and multiple-input multiple-output (MIMO) wiretap channels. Zhao and Pan (2016) investigated the secrecy outage performance of decode-andforward and randomize-and-forward cooperative systems, considering the MRC scheme with weighting errors.…”

“…However, Shrestha and Kwark (2014), Hu and Tao (2015), and Zhao and Pan (2016) did not consider the ergodic secrecy capacity (ESC), which is one of the most important parameters in physical layer security (Wang et al, 2014a;2014b). Because of the rapid increase in the demand for wireless communication services, the capacity of fading channels is increasingly becoming a main concern in the design of wireless communication systems (Khatalin and Fonseka, 2006).…”

This paper investigates the secrecy performance of maximal ratio combining (MRC) and selection combining (SC) with imperfect channel state information (CSI) in the physical layer. In a single-input multipleoutput (SIMO) wiretap channel, a source transmits confidential messages to the destination equipped with M antennas using the MRC/SC scheme to process the received multiple signals. An eavesdropper equipped with N antennas also adopts the MRC/SC scheme to promote successful eavesdropping. We derive the exact and asymptotic closed-form expressions for the ergodic secrecy capacity (ESC) in two cases: (1) MRC with weighting errors, and (2) SC with outdated CSI. Moreover, two important indicators, namely high signal-to-noise ratio (SNR) slope and high SNR power offset, which govern ESC at the high SNR region, are derived. Finally, simulations are conducted to validate the accuracy of our proposed analytical models. Results indicate that ESC rises with the increase of the number of antennas and the received SNR at the destination, and fades with the increase of those at the eavesdropper. Another finding is that the high SNR slope is constant, while the high SNR power offset is correlated with the number of antennas at both the destination and the eavesdropper.

“…However, due to the fact that training periods are separated from signal transmissions in time, weighting factors derived from the training may not accurately estimate the current CSI. To solve this problem, [9]- [11] modeled and analysed the effect of Gaussian estimation errors. Specifically, authors in [11] investigated the impact on secrecy performance in a wiretap channel under the constraint of single transmit antenna configuration.…”

We analyse the secrecy outage performance of transmit antenna selection/maximal-ratio combining systems with the consideration of weighting errors. NA, NB, and NE antennas are assumed to be equipped at the transmitter, the legitimate receiver, and the eavesdropper, respectively. We derive generalized secrecy outage probability and introduce a statistical analysis tool, saddlepoint approximation, to investigate the asymptotic behavior. A weighted sum of diversity orders range from NA to NANB can be obtained when the eavesdropper's average signal-to-noise ratio is constant. At last, simulation results demonstrate the theoretical analysis.

“…Secondly, for techniques at the receiver side, the multiple receive antennas have been adopted to mitigate fading effect and enhance channel quality [1], [9]. Thirdly, some techniques are implemented at neither transmitter nor receiver side, for example, cooperative jamming strategy at external helpers was studied in [10] to confuse the eavesdroppers.…”

Abstract-Recently, there has been a growing interest in applying multiple antennas to achieve information-theoretic security in wireless communication networks. In this paper, we consider the transmission of common confidential data from a singleantenna transmitter to multiple multi-antenna receivers in the presence of multiple multi-antenna eavesdroppers. Both the receivers and eavesdroppers employ maximal-ratio combining (MRC) to combine the signals received at multiple antennas. For the considered system, we derive its connection outage probability and secrecy outage probability to characterize the reliability level and the security level, respectively. Numerical results are also provided to analyze the tradeoff among the reliability and security performances and the number of antennas (or nodes) of either receivers or eavesdroppers.Index Terms-Physical layer security, secrecy outage probability, multiple antennas, multicast
