Outage probability analysis of FSO system with Airy beam as carrier

Based on the scintillation index of Airy beam and exponentiated Weibull channel model, analytical expressions of outage probability for free-space optical (FSO) communication links with Airy beam as a signal carrier under weak atmospheric turbulence and on-off keying modulation scheme are derived. The outage probability at various propagation distances, transverse scale factors and exponential decay factors has been evaluated. And we compared the outage probability of FSO links with Airy beam and Gaussian beam as a signal carrier. The results show that the outage probability of FSO links with Airy beam as carrier decreases with the increase of threshold parameter and increases with the increase of propagation distance. When the transverse scale factor of Airy beam is about 2 cm, a lower outage probability can be obtained. And the smaller the exponential decay factor of the Airy beam, the lower the outage probability. Under the same source power or source width, the outage probability of FSO links with Airy beam as a carrier is significantly lower than that of FSO links with Gaussian beam as a carrier. The results of this research have some reference significance for the application of Airy beam in FSO communication system.
