In this paper, we investigate the secure performance of multi-antenna decode-and-forward (DF) relaying networks where the Nakagami-m fading channel is taken into account. In practice, the joint impact of residual transceiver hardware impairments (HIs) and channel estimation errors (CEEs) on the outage probability and intercept probability is taken into account. Considering HIs and CEEs, an optimal transmit antenna selection (OTAS) scheme is proposed to enhance the secure performance and then a collaborative eavesdropping scheme is proposed. Additionally, we present main channel capacity and intercept capacity of the multi-antenna DF relaying networks. More specifically, we derive exact closed-form expressions for the outage and intercept probabilities. To obtain useful insights into implications of parameters on the secure performance, the asymptotic behaviors for the outage probability are examined in the high signal-to-noise ratio (SNR) regime and the diversity orders are obtained and discussed. Simulation results confirm the analytical derivations and demonstrate that: 1) As the power distribution coefficient increases, OP decreases, while IP increases; 2) There exist error floors for the outage probability at high SNRs, which is determined by CEEs; 3) The secure performance can be improved by increasing the number of source antennas and artificial noise quantization coefficient, while as the number of eavesdropping increases, the security performance of the system is reduced; 4) There is a trade-off between the outage probability and intercept probability. secrecy outage probability (SOP) and strictly positive secrecy capacity (SPSC). Regarding the non-homogeneous fading environments, the authors in [11] explored the secrecy performance of Wyner's model over α − µ fading channels. With the help of moment matching method, the authors in [12] derived approximate expressions for the SOP and SPSC over κ − µ shadowed fading channels. On a parallel avenue, cooperative relaying is another promising technique to further improve the spectral efficiency and enhance the coverage of wireless networks [13-15], and thus it attracts plenty of researchers to investigate the security issues of cooperative networks [16-23]. In [16], the authors analyzed the secrecy performance of amplify-and-forward (AF) relay systems over generalized-K fading channels, where three metrics for the SOP, average secrecy capacity (ASC) and SPSC were analyzed. To improve the PLS against eavesdropping attacks, the optimal relay selection (ORS) scheme was proposed for AF and decode-and-forward (DF) relay networks and the intercept probability (IP) for the proposed scheme was derived in closed-form [17]. From the perspective of energy harvesting, the authors in [18] proposed a cooperative transmission scheme for the AF and DF relay networks under the condition of an eavesdropper, where the relays can harvest energy from radio-frequency (RF) signals of a source through power-splitting protocol. In the existing research results, the researchers discuss...

“…The performance limits of massive MIMO systems under practical antenna selection algorithms using large scale system analysis that maximizes the energy efficiency are studied in [18]. In [19], the impacts of transmit antenna selection on the secrecy performance of massive MIMO systems are analyzed. It is found that in some wire tap settings under antenna selection, the increase in the number of active antennas improves the secrecy performance of the system up to some optimal number.…”

“…In [17] and [18], antenna selection algorithms are proposed with the purpose of attaining only utmost energy efficiency rather than considering sum rate maximization, interference, and complexity analysis. The effect of transmit antenna selection on the secrecy performance of massive MIMO systems is discussed in [19]. In [20], the complexity of antenna selection increases with the number of antennas which is very high for a massive MIMO system.…”

This paper focuses on an efficient antenna selection strategy for a distributed massive MIMO system. The objective of the proposed algorithm is to attain ergodic achievable rate as much as possible with antenna selection in a constrained capacity limited system. In this proposed work, the initial selection of antenna set is based on channel amplitude and correlation which then follows an iterative approach in order to select the best subset of transmit antenna elements from the overall antenna set. The proposed scheme significantly outperforms, in terms of ergodic rate with low complexity, the prevailing transmit antenna selection methods. Simulation results show that the performance of the proposed antenna selection method is close to select all transmission with a minimum throughput loss. Thus the proposed method is best suited for a large scale distributed Massive MIMO system without degradation in system performance and is of low computational complexity.

“…In the past years, many researches on antenna-selectionaided MIMOME channels were presented [6]- [10].

“…Later, the achievable secrecy performance of MIMO wiretap channels in the presence of imperfect CSI was analyzed in [9]. In contrast to the explicit analysis in [6]- [9], Asaad et al,in [10] proposed asymptotically approximated results for both the average secrecy rate and the SOP in the limit of largescale MIMOME systems under the norm-based TAS protocol. However, all these aforementioned works focused on the Gaussian input assumption.…”

This paper studies the secrecy performance of multiple-input multiple-output (MIMO) wiretap channels, also termed as multiple-input multiple-output multiple-eavesdropper (MIMOME) channels, under transmit antenna selection (TAS) and BPSK/QPSK modulations. In the main channel between the transmitter and the legitimate receiver, a single transmit antenna is selected to maximizes the instantaneous Signal to Noise Ratio (SNR) at the receiver. At the receiver and the eavesdropper, selection combination (SC) is utilized. By assuming Rayleigh flat fading, we first derive the closed-form approximated expression for the ergodic secrecy rate when the channel state information of the eavesdropper (CSIE) is available at the transmitter. Next, analytical formulas for the approximated and asymptotic secrecy outage probability (SOP) are also developed when CSIE is unavailable. Besides theoretical derivations, simulation results are provided to demonstrate the approximation precision of the derived results. Furthermore, the asymptotic results reveal that the secrecy diversity order degrades into 0 due to the finitealphabet inputs, which is totally different from that driven by the Gaussian inputs.
