Abstract This paper presents high altitude platform free space optics (HAP-FSO) channels using various filtering operations for fifth generation (5G) system. Performance analysis is done utilizing different types of optical filters such as Bessel, Trapezoidal, Gaussian and Rectangular. A comparison is carried out between our proposed scheme and reported counterpart. HAP-FSO performances have been investigated by referring to different factors such as transmission distance, transmitting aperture diameter, beam divergence, transmitter aperture diameter, and receiver diameter. Simulation analysis is carried out in highly recognized software tool called Optisystem to validate the implementation and performance of the proposed system. It is found that the most extreme quality services can be accomplished via utilizing Gaussian optical channel in comparison with distinctive optical channels. Simulation results also confirm the proposed system for error free transmission at bit error rate (BER) of 10-9 for all types of filters at 10Gbps with in favor to Gaussian filter for the same number of users.
