摘要

为了测量和表征水下光通信信道的衰落，建立了双发双收空间分集系统。该系统允许收集实验室产生的由湍流、粒子和气泡引起的光束中断。收集到的数据使用为大气测量开发的衰落度量来表征。空间分集可以减少接收端观测到的衰落量，从而提高系统性能。

A spatial diversity system to measure optical fading in an underwater communications channel

A two transmitter two receiver spatial diversity system was built for measuring and characterizing fading in underwater optical communication channels. The system allows the collection of laboratory generated interruptions of the optical beam from turbulence, particles, and bubbles. The data collected is characterized using fading metrics developed for atmospheric measurements. Spatial diversity is shown to decrease the amount of fading observed at the receiver to improve system performance.
