ASER Performance Analysis of Decision Threshold-Based Hybrid FSO-RF Turbulent Link

Time hysteresis-switching algorithm assisted dual-hop relaying for hybrid FSO/RF system

“…Through the simulations, the parameters like α and β for FSO link is evaluated from Equation (1) of [36] by the same authors and related investigations. Considering perfect alignments between transmitter and receiver aperture, i.e., no pointing error (a point receiver is used, D ≪ L j leading to d = 0 from [36]). Parameters α and β are function of χ 2 which is dependent on parameters 𝙲 n 2 and L j as mentioned in Equation ( 1) and related investigations of [36].…”

“…Considering perfect alignments between transmitter and receiver aperture, i.e., no pointing error (a point receiver is used, D ≪ L j leading to d = 0 from [36]). Parameters α and β are function of χ 2 which is dependent on parameters 𝙲 n 2 and L j as mentioned in Equation ( 1) and related investigations of [36]. It is assumed that the total link distance from source (S) to destination (D), L S−D = L S−R + L R−D and L S−R = L R−D = 0.5 L S−D as well as Nakagami-m distribution perfectly models the fading over mm-RF link [13][14]16] and further considered that 𝑚 𝑆−𝐷 = 𝑚 𝑆−𝑅 = 𝑚 𝑅−𝐷 = 𝑚 = 5.…”

“…Thus we find the generalised Meijer G-function of two-variables [36]. The exact expression of 𝐵 𝐶,𝑆−𝑅 𝑓𝑠𝑜 is expressed as By putting Equations ( 11), (21), and (25) in Equation (A3), and use of Equation (9.301) of [28] in expansion of the Meijer G-functions, and the integral has been calculated using Equation (3.191.1) of [28].…”

“…In this postscript, we derive the asymptotic-SER analysis of blended FSO/RF system and express all the terms of Equation (36). With the help of Equation (07.34.06.0040.01) of [31] and Equations ( 9) and ( 11), the outcome expression along with Equation ( 24) has been putted in Equation (36) From Equation (C4), the terms Ј 𝑥 3,𝑛 1 ,𝑘 and 𝑥 3,𝑛 1 ,𝑘 have been mentioned in Table V.…”

“…where Г(•) is the gamma-integral function and the rest parameters details of above Equation ( 7) have been mentioned in Equation ( 1) of [36] by the same authors and related investigations. Therefore, Equation ( 7) can be represented as…”
