On the Effect of Correlated Sways on Generalized Misalignment Fading for Terrestrial FSO Links by Ruben Boluda-Ruiz, Antonio Garcia-Zambrana, Beatriz Castillo-Vazquez, Carmen Castillo-Vazquez

“…In the current paper, we generalize this previous approach by misalignments with correlated sways since both the horizontal displacement and the elevation are not necessarily uncorrelated RVs in potential FSO applications. A statistical pointing error model is proposed, where not only is the laser beam width, detector size, and the effect of nonzero boresight and different jitter variances for each axes taken into account, but the effect of correlated sways is also taken into account. …”
