Hybrid RF/FSO system solves the problem of the effects of severe weather on FSO,and improves system availability.Considering the combined effects of the atmosphere turbulence and pointing errors on the average channel capacity,the average channel capacity of the hybrid RF/FSO system is investigated under exponentiated Weibull atmosphere turbulence.The closed-form expressions for average channel capacity are derived based on a Meijer’s G function.The relationship between the average channel capacity and the SNR under different parameters such as the atmosphere turbulence,the normalized jitter standard deviation and the normalized beam-width is analyzed by simulation.
