We experimentally evaluated performance of a mode diversity receiver in severe fading
channels of emulated LEO-to-ground link. Digital combining of three modes using adaptive …

In this paper, new expressions of the channel-correlation coefficient and its components (the
large-and small-scale channel-correlation coefficients) for a plane wave are derived for a …

The satellite-to-ground communications systems are a significant part of the future
communications network. Meanwhile, the large capacity is also one of the goals pursued by …

We propose and demonstrate a temporally and spatially incoherent spectrum-sliced light
source for scintillation mitigation in free-space optical (FSO) communications. For the …

Free-space optical communication (FSOC) systems with variable data-rates can support
different missions with different transmission distances and ensure reliable transmission in …

The coherent receiving method can improve the sensitivity of an optical signal receiver for
free space optical communication system effectively. To implement coherent receiving, the …

High sensitivity, small size, light weight and low power are the most critical requirements for
the lasercom terminals used in free space optical communication (FSOC) systems. Coherent …
