Abstract
Optical link from ground to space is susceptible to turbulence induced fades that can last from a fraction of millisecond to longer than 10ms. Unmitigated, the fade can lead to frequent drop outs and unacceptable link performance. In this paper, we describe the system design tradeoff for various fading mitigation approaches, and concluded that channel coding is the most viable approach to provide reliable data transmission. The paper then discusses the design trades for a channel coder/interleaver for an optical ground-space feeder link.
