“…Due to the extensive coverage of WCNs, the researches on PLS of various fading models have been widely concerned by scholars [25][26][27][28][29][30]. The PLS over α-μ channels was analyzed [25], where SPSC and the upper bounds of SOP were deduced.…”

With the progress of communication technology, the increasing wireless devices are hooked up the networks, and the consequent security problems cannot be ignored. At present, the solutions mainly include secret key system and physical layer security (PLS). However, secret key system that relies on highly complex algorithms for encryption and decryption still has the risk of being cracked by powerful computers. In this paper, the PLS of Beaulieu‐Xie fading channels is studied. To improve the transmission quality and support higher speed data transmission, the single‐input multiple‐out (SIMO) system considered is the Wyner eavesdropper model with decoding and forwarding (DF) relay over Beaulieu‐Xie fading. The closed‐form theoretical formulas for secure outage probability (SOP) and strictly positive secrecy capacity (SPSC) are obtained by complex unified functional representation, which includes two cases: and . Moreover, the theoretical formulas are verified by Monte Carlo results. By comparing the simulation results with the theoretical analysis, the authors discussed the factors to improve the secure performance. Experiments show that the larger ratio of , the smaller ratio of , smaller signal‐to‐noise ratio (SNR) of eavesdropping channels, smaller threshold and more legitimate antennas are beneficial to the improvement of anti‐interference capability for the relay networks with Beaulieu‐Xie distributions when the legal channel link R→D is in a state of high SNR.

“…Inspired by Wayner's work, investigations of the attainable secrecy capacity against eavesdropping were addressed in [24] for the broadcast channel and in [25] for the Gaussian channel. Using the information theoretic point of view, researchers have focused on investigating the effect of the use of different channel conditions [26][27][28] and on different channel types [29][30][31][32][33].…”

Secrecy and BER analysis of antenna sequence spatial modulation: An information theoretic approach

5G and future generation networks require physical layer security (PLS) to reinforce the security at the higher communication layers. A novel technique of securely transmitting data in a wireless network is presented, by ensuring its security and reliability on the physical layer. Information is encoded in two domains: the spatial domain, in terms of the sequence of transmitting antennas and in the signal domain, in terms of the symbol that the antennas transmit. Hence the name antenna sequence spatial modulation (ASSM). The case of three antennas is presented, where each antenna transmits the same symbol of the two possible symbols, of the bipolar phase shift keying (BPSK) modulation, in one of the three time slots. Both the transmitter and the receiver have a mapper table relating the antenna transmitting sequence and the symbol transmitted to a code word. Using the information theoretic approach, the performance analysis of the system is presented through the bit error rate (BER) and the secrecy capacity metrics on Rayleigh fading channel. The comparison of simulation and analytical results are presented. It is inferred that the ASSM has a higher secrecy rate than the conventional spatial modulation (SM), albeit at a lower spectral efficiency.

Summary In this work, we have comprehensively investigated the impact of non‐linearity (α − μ) and shadowing (inverse gamma) collectively over the wireless channel. To this effect, an approximate closed‐form probability density function (PDF) expression is derived over α − μ/inverse gamma fading channel by employing Gauss–Laguerre quadrature polynomial. The accuracy of the proposed approximate solution is validated through the Kullback–Leibler divergence test. Subsequently, the proposed solution is utilized in the development of various fundamental statistics like commutative distribution function (CDF), moment generating function (MGF) and nth moment. This contribution also includes the derivation of coding gain and diversity gain to study average symbol error probability (SEP) with MRC and EGC diversity. It is observed that diversity gain is independent of shadowing and as the channel condition improves, the coding gain decreases. Finally, the closed‐form solutions of spectral efficiency under different adaptive transmission policies are also developed specifically, optimal power and rate adaptation (OPRA) and effective capacity along with simpler low‐ and high‐power expressions. Monte‐Carlo simulations are utilized to validate the proposed analytical and numerical results.
