“…Then, the third term of (75) can be expressed as (78), where the last line is found after applying Lemmas 4, 7, 8, and 12. Finally, after plugging (76), (77), and (78) back into (75) and several simplifications, we find (12). The proof is concluded by replacing Equations (11) and (12) into the definitions of κ and θ, given by (71) and (69), respectively.…”

It is known that the Central Limit Theorem (CLT) is not always the most appropriate tool for deriving closed-form expressions. We evaluate a Single-Input Single-Output (SISO) system performance in which the Large Intelligent Surface (LIS) acts as a scatterer. The direct link between the transmitting and receiving devices is negligible. Quantization phase errors are considered since the high precision configuration of the reflection phases is not always feasible. We derive exact closed-form expressions for the spectral efficiencies, outage probabilities, and average symbol error rate (SER) of different modulations. We assume a more comprehensive scenario in which $b$ bits are dedicated to the LIS elements' phase adjustment. From Monte Carlo simulations, we prove the excellent accuracy of our approach and investigate the behavior of power scaling law and power required to reach a specific capacity, depending on the number of reflecting elements. We show that the LIS with approximately fifty elements and four dedicated bits for phase quantization outperforms the conventional system performance without LIS.

“…Apart from the aforementioned fading model, other models, including the composite fading model and cascaded fading model, are also widely used to characterize some wireless communication scenarios. In particular, the cascaded fading model demonstrates feasibility and applicability in modeling the multi-hop cooperative communications [11], [18], mobile-to-mobile (M2M) communication [19], [20], and radio-frequency identification (RFID) pinhole channels [21], etc.…”

In this paper, we have investigated the physical layer security over cascaded Fisher-Snedecor F fading channels in the presence of randomly distributed eavesdroppers. To characterize the eavesdroppers' intercept capability, both the conceptual k-th nearest and best eavesdroppers are introduced. The probability density function (PDF) of the k-th nearest and best eavesdropper is characterized. The probability of interception, Pint, is correspondingly regarded as the secrecy metric, and is further derived with closed-form expressions in terms of Fox's H-function. For the purposes of providing more insights, the asymptotic behavior of the intercept probability is also provided. To explore the effects of the eavesdroppers' density and the channel fading conditions on the secrecy performance, we have performed the Monte-Carlo simulation and compared our analytical results with the simulated ones. One can find that our analytical results are successfully verified by the simulation results.

This paper studies the physical layer security of a vehicular communication network in the presence of interference constraints by analysing its secrecy capacity. The system considers a legitimate receiver node and an eavesdropper node, within a shared network, both under the effect of interference from other users. The double-Rayleigh fading channel is used to capture the effects of the wireless communication channel for the vehicular network. We present the standard logarithmic expression for the system capacity in an alternate form, to facilitate analysis in terms of the joint moment generating functions (MGF) of the random variables representing the channel fading and interference. Closed-form expressions for the MGFs are obtained and Monte-Carlo simulations are provided throughout to validate the results. The results show that performance of the system in terms of the secrecy capacity is affected by the number of interferers and their distances. The results further demonstrate the effect of the uncertainty in eavesdropper location on the analysis.
