The next generation free-space optical communications infrastructure will need to support a
wide variety of space-to-ground links. As a result of the limited size, weight, and power on …

Space-to-ground optical communication systems can benefit from reducing the size, weight,
and power profiles of space terminals. One way of reducing the required power-aperture …

Space terminals for free-space optical communication systems are under constant pressure
to reduce their size, weight, and power profiles. Ground terminals with large collection areas …

We report investigations on the mode diversity receiver applied in optical links from low-
earth-orbital satellites to a ground terminal. We numerically simulated temporal power …

Coherent, free-space optical communication technology offers near-quantum-limited
receiver sensitivity and high spectral efficiency compared to conventional direct detection …

Accurate knowledge of information data capacity between a spacecraft and optical ground
stations is of utmost importance for assessing the feasibility of laser downlinks in future high …

We study the performance of diversity combining techniques applied to synchronous laser
communication through the turbulent atmosphere. We assume that a single information …

We study the performance of various binary and nonbinary modulation methods applied to
coherent laser communication through the turbulent atmosphere. We compare the spectral …

Spatial diversity reception is an effective technology to mitigate the atmospheric turbulence
effect on the performance of the coherent free space optical (FSO) communications …

High-speed free-space optical communication systems have recently used fiber-optic
components. The received laser beam in such a system must be coupled into a single-mode …
