Abstract
In this study, a comprehensive model for evaluating the performance of hybrid RF/FSO (Radio Frequency/Free Space Optics) systems is introduced. The recently presented Gamma-Rician model was employed for the statistical characterisation of FSO turbulence, while the Nakagami-m fading model was utilised for RF propagation modelling. We provide closed-form expressions for the Cumulative Distribution Function (CDF) of observed Signal-to-Noise Ratio (SNR) at reception, along with closed-form expressions for the Average Bit Error Rate (ABER) using the Coherent Binary Phase Shift Keying (CBPSK) modulation scheme. Two transmission methods in relay hybrid RF/FSO systems have been analysed: One-Hop and Multi-Hop transmissions. By capitalising on these expressions, we have evaluated the ABER performance of these systems as a function of various parameters, highlighting the robustness of hybrid configurations under differing operational conditions.
