Abstract
In free-space optical communications systems, a number of mechanisms can produce a temporally fluctuating signal-to-noise ratio (SNR), giving rise to fluctuations in the bit error probability that have time constants which are extremely long in comparison to the bit length. Among these mechanisms are pointing errors and atmospheric turbulence. This paper presents simple methods of properly accounting for the fades and surges in optical communication system design through the concepts of burst error and burst error probability. Examples are given for the cases of atmospheric turbulence and pointing errors.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
