“…wherein the average power of the scattered component independent of the LOS component is 2b 0 (1 − ρ) and that coupled to LOS is 2b 0 ρ [35]. Both these terms are related by ρ, which denotes the amount of scattering power coupled to the LOS component, and it varies between 0 and 1.…”

This study focuses on the analysis of a decode-and-forward relay-based asymmetric radio frequency-free space optical (RF-FSO) communication system. These types of communication systems are of very high speed, secure, and costeffective. Such systems can be used to provide the last-mile access to many household users and can provide temporary network access during disasters and link failures. In the communication model analysed, the RF path is considered as Rayleigh fading, and the FSO path is considered as Málaga (ℳ)-distributed turbulence fading with the pointing error. Two types of detection schemes consisting of intensity modulation/direct detection and heterodyne detection are considered at the receiver for the analysis. For this cooperative communication system, novel mathematical expressions for the cumulative distribution function, probability density function, and moment generating function of the end-to-end signal-to-noise ratio are derived. With the aid of these statistical characteristics, new closed mathematical formulations are obtained for outage probability and the average bit error rate for different binary and M-ary modulation approaches.

“…In [28,29], the authors considered the power series method in order to analyse the RF-FSO link. In [35], the channel capacity was derived for the RF-FSO system with the RF link modelled as Nakagami-m fading and the FSO link as gamma−gamma fading.…”

“…Different fading channels for RF links and atmospheric turbulence models with pointing errors for FSO links were investigated such as Rayleigh, Nakagami‐m, κ–μ or η–μ distributions for RF links [8–10] and gamma–gamma, exponential Weibull, M‐distribution, double generalised gamma (DGG) models for FSO links [11–13]. Moreover, novel closed‐form expressions for outage probability (OP), symbol error rate (SER) and ergodic capacity [14–16] were further presented based on mixed RF/FSO system. On the basis of this the performances of different relay strategies were evaluated including decode‐and‐forward (DF) relay and amplify‐and‐forward (AF) relay [17, 18].…”
