Gamma-gamma turbulence-based performance modeling of underwater NOMA visible light communication systems with imperfect CSI and SIC

Key Points

• Performance modeling indicates a significant impact of gamma-gamma turbulence on communication efficiency.
• The analysis revealed that imperfect channel state information notably degrades system performance.
• Non-orthogonal multiple access was utilized to enhance the capacity of visible light communication systems.
• Successive interference cancellation was a critical technique to improve signal reliability under turbulent conditions.
