Average capacity of airborne optical links over exponentiated Weibull atmospheric turbulence channels

Exact distributions for bit error rate and channel capacity in free‐space optical communication

“…However, for our analysis, we focus mainly on the log-normal, gamma-gamma, and K distributions. Interestingly, unlike the exact expressions for the averages, which contain higher transcendental functions like Meijer G [15,16,19,25], our exact expressions for the PDFs involve relatively simple special functions. By evaluating these results we find that there are several instances when the PDF is not 'localised' around the average value and, instead, is rather dispersed.…”

“…As a consequence of the stochastic nature of the optical signal, these quantities behave as random variables. Typically, investigation involving these measures remains restricted only to their respective averages (first moments) [4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. However, since the full information concerning a random variable is encoded in its distribution, the average values may not capture the true behaviour of these metrics.…”

Average Ber Analysis of Free-Space Optical Communications With Adaptive Threshold Technique Over Exponentiated Weibull Distribution

“…In [10], the advantages and disadvantages of FSO communication as well as various turbulence channel models have been discussed. Reference [11] has analyzed the average channel capacity of airborne optical links by using EW model. Reference [12] has investigated the performance of pulse position modulation (PPM) under atmospheric turbulence.…”
