Exponentiated Weibull model for the irradiance probability density function of a laser beam propagating through atmospheric turbulence

SER performance analysis of MPPM FSO system with three decision thresholds over exponentiated Weibull fading channels

“…The expressions for calculation of these parameters have been derived in [14] with a group of specific values obtained by fitting the experimental results. As known, when the received signal is detected slot by slot, the output of the sampler can be modeled as follows…”

“…Particularly, both of them have been used to study the effects of aperture averaging [7,12]. Recently, one novel fading model named exponentiated Weibull (EW) distribution was proposed by Ricardo Barrios and Federico Dios [13,14]. Their studies show that EW distribution fits more accurately with the actual PDF data than GG and LN distributions under all aperture averaging conditions and weak-to-strong turbulence regime [14].…”

After that, the error performance of OOK and BPSK modulated FSO systems over EW fading channels has been further investigated by [15][16][17] with the effect of aperture averaging taken into account.…”

Symbol error rate performance analysis of soft-decision decoded MPPM free space optical system over exponentiated Weibull fading channels

“…Among them, EW distribution is a novel one, which is proposed and experimentally verified by Barrios and Dios in Refs. [6,7]. Their study revealed that this distribution could model the PDF of irradiance in weak-to-strong turbulence regimes under all aperture-averaging conditions.…”

“…Their study revealed that this distribution could model the PDF of irradiance in weak-to-strong turbulence regimes under all aperture-averaging conditions. Most importantly, apart from the perfect fit to right tail of the PDF, the left tail of EW distribution is much better than G-G and LN distributions, which is essential in assessing the outage and error performances [7] . Due to this advantage, some works concerning the performance of an FSO communication system over EW fading channels have been reported in these years [8][9][10][11][12] .…”
