| Summary: | Intensity modulation/direct detection (IM/DD) multi-hop Free Space Optical link system and mixed single-hop RF link performance in serial relaying are examined for the 5G centralized radio access network (C-RAN). While the FSO link utilises a Gamma-Gamma (G-G) distribution channel, the RF link employs a Generalised Nakagami-m fading channel. For the serial relaying method, RF employs the M-ary Quadrature Amplitude Modulation (M-QAM) modulation scheme, whereas FSO uses the Binary Pulse Position Modulation (BPPM) scheme. The decode and forward technique is used in relays. The proposed system’s performance is estimated regarding Average Symbol Error Rate (ASER), Ergodic Channel Capacity, and Outage Probability. The proposed system leverages Reed Solomon’s coding techniques to enhance its performance. The effectiveness of the system is assessed by comparing coded and uncoded systems under various atmospheric weather conditions, including atmospheric turbulence (AT) and pointing error (PE). Monte Carlo simulation validates the results, demonstrating how the system can support 5G applications. |
