Analysis of differential-phase-shift keying protocol for 1.55μm up-conversion single-photon detector
2008 Edition, January 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The properties of 1.55 mum up-conversion single-photon detector are analyzed using the differential-phase-shift keying (DPSK) protocol. We compare the error rate and the communication rate as a function of distance...

Performance analysis of differential-phase-shift-keying optical receivers in the presence of in-band crosstalk noise
2005 Edition, Volume 23, December 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In-band crosstalk can pose important limitations in an all-optical wavelength-division-multiplexed (WDM) network. Recent studies have demonstrated that differential phase shift keying (DPSK), can tolerate higher in-band crosstalk-noise levels compared to amplitude...
