Average Bit Error Rate (BER) expression of free-space optical (FSO) communication links with Airy beam as signal carrier under weak atmospheric turbulence and on-off keying (OOK) modulation scheme is derived based on scintillation index of Airy beam and Exponentiated Weibull (EW) channel model. The average BER has been evaluated at different transverse scale factors and exponential decay factors of Airy beam and link distances. And comparison of the average BER of FSO links with Airy beam and Gaussian beam as signal carrier has been carried out. The simulation results show that the average BER of FSO links with Airy beam as carrier decreases with the increase of mean signal to noise ratio (SNR) and increases with the increase of transmission distance. When the transverse scale factor is about 1.5cm, a lower average BER can be obtained. And the smaller the exponential decay factor is, the lower the average BER is. Under the same atmospheric turbulence condition, the average BER of FSO links with Airy beam as carrier is obviously better than that of FSO links with Gaussian beam as carrier. The results of this research have some significance for the application of Airy beam in FSO system.

“…The scintillation index is the measure of the turbulence strength, where lower values lead to less intensity variations and, vice versa, higher index values result in the higher values of turbulences. Refraction index Cn 2 [6], is a variable that depends on the geographic location, altitude and time of the day. The refraction deviation index results in scintillation, the deviation and spread of the beam.…”

In this paper performance analysis of colour image Free Space Optics (FSO) transmission over Double Generalized Gamma (DGG) turbulence communication channel is carried out. At the reception side, we have used an average bit error rate (ABER) for reconstructed image performance measure, as the function of FSO link transmission parameters, such as propagation distance, Rytov variance and turbulence shaping and severity parameters (γ1, γ2, m1, m2). Obtained results cover a large number of colour image FSO transmission scenarios, for Gamma-Gamma, Double-Weibull and K turbulence models channels considered as special cases. Index Terms-Free-space optical communication; channel models; double generalized gamma channel; image processing. I. INTRODUCTION Development of FSO technology allows high-speed transmission over free space [1], [2]. Widespread use of FSO communication systems has arisen due to its obvious advantages, which especially occur in satellite communications, terrestrial and last-mile connections. Main advantages over RF systems (beyond high speed transmission), are the absence of co-channel interference and crosstalk during transmission of high data flow and usage of small transmission power and no need for spectrum licensing. One of the basic assumption for successful application of FSO system is the existence of Line of Sight (LOS) between transmitter and receiver, although there also may exist relay realizations of FSO systems. However, there are also a few drawbacks that can significantly impair performance of FSO transmission. One of them are weather conditions along transmission path, manifested in the form of scintillation, random fluctuations of the irradiation of optical beam caused by turbulences. Namely, temporal and spatial fluctuations that occur are consequence of the variations of refraction index (caused by fog, rain, haze), which manifest as irradiation
