The multi-rate DPSK format, which enables efficient free-space laser communications over a
wide range of data rates, is finding applications in NASA's Laser Communications Relay …

In this paper, a pulse positioned-differential phase shift keying technique is proposed to
enhance the data rate in free space optical communication. Using the schematics of …

We present the transponder design and verification to obtain over 10 Gbit/s capability for an
optical feeder link. The transponder employing a transmitter and a receiver supports …

Recently, we demonstrated a multi-rate DPSK modem with high-sensitivity over a wide
dynamic range, which can significantly benefit performance and cost of NASA's Laser …

The low-orbit satellite communication can provide users with low-delay and ultra-wideband
communication services worldwide. By the wide available bandwidth and immunity to …
