Study of possible hardware-related malfunctions in mixed messaging system (RF/FSO) with CSI

In this study, we will propose an optical data transmission system that operates on high-level frequencies and characterized by double hop (RF) in the free medium with several stages of encryption, decoding, transmission, retransmission, amplification and redirection operations with appropriate relay schemes so that the channels we work on are subject to For Rayleigh frequency, in addition to a special type of distribution (for atmospheric turbulence) called the (M) distribution, where partial relays will be proposed in addition to the old channel information for the best redirection of the signal so that we can achieve the desired signal either after the process of modification or modification to the intensity In this study, we will neglect the errors and defects of manufacturing devices and we will assume that the devices we are working on are ideal devices (it works at a low and low data rate only), and therefore we will impose a system that has a general model for the devices we are working on to study our system and the effect of referring to Interference and noise (SNR) but not working with high values Faults in this case will have little effect when the (SNR) ratio is low. For the probability of interruption (in the transmission). We will do the mathematical derivations and also for the amplitude (ergodic) but the error from the code we get through mathematical operations and integration with the observation method. The system works through convergence operations.
