摘要
水下无线光通信(UWOC)是一种新兴的高速水下通信技术,因其拥有传输带宽高、抗电磁干扰能力强、功耗低和体积小等优点,在学术界和工业界逐渐引起广泛关注。尽管光作为信息载体在水下传输时存在较大衰减,但其传输距离仍然可达百米级别,足以满足传感器数据传输的距离要求。然而,目前UWOC技术仍处于早期发展阶段,大部分UWOC系统的实验仅在实验室水箱开展,且性能测试方法各不相同,缺乏统一的性能测试模型和方法。为更客观地评估UWOC系统的性能,文章尝试提出UWOC系统的一般测试方法,建立测试模型,并总结系统评价指标,以促进UWOC技术的发展。
Underwater Wireless Optical Communications(UWOC)is an emerging high-speed underwater communication technology that has gradually attracted widespread attention in academia and industry due to its advantages of high transmission bandwidth,electromagnetic interference resistance,low power consumption,and small size.Although light has a larger attenuation in underwater transmission than acoustic wave,its transmission distance can still reach hundreds of meters,which is sufficient to meet the requirements for sensor data transmission.However,UWOC technology is still in an early stage of development,with most experiments being conducted only in laboratory water tanks.Therefore,unified performance testing models and methodologies are required due to different testing methods for UWOC.In order to objectively evaluate the performance of a UWOC system,this article attempts to propose the general testing method,model and evaluation indicators for UWOC systems,to promote the development of UWOC technology.
