Performance analysis of optical wireless communications on long- range links

摘要

Optical wireless communications over long-range atmospheric links experiences strong fading that heavily influences the performance of communication systems. Most research on this topic is focused on simulation or measurement of the link performance in terms of the bit error ratio. In this work a statistical channel model derived from measurements is used for simulations of the link performance on packet layer. For analysis of a possible improvement of packet layer performance by error protection techniques like forward error correction and automatic repeat request, additional simulations are done. All simulations are done for several communication scenarios like the maritime environment, land mobile and air-to-ground links.
