In this paper, have been deduce the performance analysis for free space optic channel (FSO) to conquer the difficulties implementation on terrestrial infrastructures, and channel leasing. At the transmitter side four channel produced by the wavelength division multiplexing (WDM) transmitter to feed to the FSO transceiver the output signals are received successfully with 5 Gbps, the free channel range is 200 m, the attenuation with the best iteration is 25 dB/km. There are 10 iterations are done by an OptiSystem software simulation package the average of total power is -34.22 dBm, and the average of maximum Q-factor is 114.43 are evaluated and seems are good based on the hole project. The low error data rates are concluded.

“…The signal‐to‐interference‐plus‐noise ratio (SINR) for the f th UE can be given as

γ_{f} = \frac{a_{f}^{2} {| g_{f} |}^{2}}{a_{n}^{2} {| g_{f} |}^{2} + \frac{1}{ρ}},

where

ρ

is the transmit SNR. Note that n th UE can decode its own signal after decoding the signal intended for f th UE using SIC 25 . The SINR requirement at n th UE to decode f th UE's signal is given by

γ_{n \to f} = \frac{a_{f}^{2} {| g_{n} |}^{2}}{a_{n}^{2} {| g_{n} |}^{2} + \frac{1}{ρ}} .

In this study, user selection‐based downlink power domain‐non‐orthogonal multiple access (NOMA) system is investigated over generalized fading channels, that is, η‐μ and κ‐μ fading channels. In particular, this system considers multiple users and out of which two users are selected to serve with NOMA principle in perfect channel state information scenario. The outage probability expressions of the system are derived with respect to the fixed target rate and the orthogonal multiple access (OMA) rate. In addition, the average sum‐rate and rate of paired users of the system are derived and compared with that of OMA. Further, the optimum power allocation coefficients are derived for the system to ensure fixed and dynamic rate requirements. The impact of imperfect successive interference cancelation on the system performance is discussed. The paper also investigates the effect of various parameters on the performance of the system. The extensive simulations show the accuracy of the derived expressions.
