摘要

本文采用蒙特卡罗仿真方法,对两种链路配置:视距反射链路和非视距反射链路的水下无线光通信性能进行了评估。对于视距链路,对准直光束和扩散光束进行比较。结果表明,与浑浊海水相比,在清洁海水中发射机波束发散对传输有显著影响。据估计,在浑浊水中,视距链路可以实现的带宽约为100 MHz,而在清洁水中则要高得多。对于非视距反射链路,带宽在清水中严格限制在20 MHz左右。

Monte Carlo simulation for underwater optical wireless communications
This paper presents the Monte Carlo simulation to evaluate the performance of underwater optical wireless communication for two types of link configuration: line-of-sight and non-line-of-sight reflective links. For line-of-sight links, comparison is made between a collimated and a diffused beam. The results demonstrate that the transmitter beam divergence has a significant impact in the transmission in clean seawater compared to turbid water. The bandwidth that can be achieved for line-of sight links is estimated to be around 100 MHz in turbid water and much higher in clean water. For non-line-of-sight reflective links the bandwidth is severely limited to around 20 MHz in clean water.
