- Abstract
In this research, we have examined the performance of a link in an underwater visible light communication (UVLC) system using an intensity-modulated/direct detection (IMDD) system. Underwater visible light communication (UVLC) plays a pivotal role in shaping the future of underwater wireless networks. In most cases, the performance of UVLC links is adversely affected by factors such as atmospheric attenuation, scattering, and turbulence, which mainly affect high data rate distance communication and the bit-error rate (BER) of the UVLC system. The utilization of highly sensitive Avalanche Photodiodes (APD) represents one of the mitigation techniques employed to alleviate the influence of atmospheric attenuation, scattering, and turbulence in UVLC systems. Both Avalanche Photodiodes (APD) and PIN photodiodes are employed as strategies to mitigate the adverse effects resulting from atmospheric attenuation, scattering, and turbulence in UVLC systems, which hinders long-distance communication with high data rate. We conducted a performance comparison, evaluating the Bit Error Rate (BER) at various data rates, for both PIN and Avalanche photodiodes. As the data rate increases, the achievable communication link distance decreases, while maintaining the targeted BER of 10 - 5 . Our observations indicate that the Avalanche Photodiode (APD) consistently exhibits superior performance when compared to the PIN photodiode.
