Receiver sensitivity is a particularly important metric in optical communication links
operating at low signal-to-noise ratios (SNRs), for example in deep-space communication …

In the field of intersatellite laser communication, there are two high-sensitivity demodulation
methods: binary phase-shift keying (BPSK) coherent detection and differential phase-shift …

Communicating information at the few photon level typically requires some complexity in the
transmitter or receiver in order to operate in the presence of noise. This in turn incurs …

The demand for high data rate in space communication links is increasing due to the growth
of space exploration missions inter-satellite, and satellite-to-Earth data transmission. Optical …

In this paper, we investigate the impact of the transmitter finite extinction ratio and the
receiver carrier recovery phase offset on the error performance of two optically preamplified …

The next generation free-space optical (FSO) communications infrastructure will need to
support a wide range of links from space-based terminals at LEO, GEO, and deep space to …

We experimentally investigate the bit error rate (BER) performance of soft-decision low
density parity check (LDPC) turbo decoding (Turbo-LDPC) in a 56Gbit/s high power …

The present work discusses highly sensitive optical communication systems as they are
used for example in inter-satellite links. Theoretical analysis about receiver sensitivity …

Fading experienced in free-space optical channels is known to impede the performance of
pulse position modulation (PPM) communication systems. In this paper, we study the effects …
