dc.description.abstract The Lunar Laser Communications Demonstration Project undertaken by MIT Lincoln Laboratory and NASA’s Goddard Space Flight Center will demonstrate high-rate laser communications from lunar orbit to the Earth. NASA’s Jet Propulsion Laboratory is developing a backup ground station supporting a data rate of 39 Mbps that is based on a non-real-time software post-processing receiver architecture. This approach entails processing sample-rate-limited data without feedback in the presence high uncertainty in downlink clock characteristics under low signal f ux conditions. In this paper we present a receiver concept that addresses these challenges with descriptions of the photodetector assembly, sample acquisition and recording platform, and signal processing approach. End-to-end coded simulation and laboratory data analysis results are presented that validate the receiver conceptual design. en_US
