Abstract: Systems and methods for optical communication through air or space are disclosed. A method includes encoding one or more data frames with a data-link layer forward error correction (FEC) code to produce a plurality of encoded data frames and transmitting the plurality of encoded data frames from a transmitter (TX) to a receiver (RX) at least partially through air or space using a plurality of optical beams. The RX identifies a corrupted encoded data frame and reconstructs the corrupted encoded data frame using a data-link layer FEC decoder operating over a plurality of non-corrupted encoded data frames.

Abstract translation: 公开了通过空气或空间进行光通信的系统和方法。 一种方法包括用数据链路层前向纠错（FEC）码对一个或多个数据帧进行编码，以产生多个编码数据帧，并将多个编码数据帧从发射机（TX）发射到接收机（RX） 至少部分地使用多个光束通过空气或空间。 RX识别已损坏的编码数据帧，并使用在多个未损坏的编码数据帧上操作的数据链路层FEC解码器来重建损坏的编码数据帧。
