This research was performed in a 4-channel 40 Gbps WDM transmission system with binary differential phase
shift keying (BDPSK) modulation.
For example, the following imaging techniques are currently supported: X-ray fluorescence (XRF), ptychography, diffraction, differential phase
contrast and X-ray absorption spectroscopy.
shift keying does not have determined symbols in constellation diagram as it is in common PSK, but it has a table of phase shifts (in degrees or radians) where is each phase shift represented with a symbol.
The higher spatial resolution allows studies of small-scale features, such as individual cumulonimbus clouds, gust front circulations, and microbursts, while the greater differential phase
sensitivity should enhance the analysis of winter storm patterns, such as crystal growth; summer storm patterns, such as the identification of electrification morphology (Caylor and Chandrasekar 1996); and general rainfall estimation applications, especially for lighter rain rates.
On the other hand differential phase
shift keying (DPSK) is a non-coherent kind of phase shift keying technique.
The proposed quadrature power divider consists of a two-section power divider in combination with a 90[degrees] [+ or -] 10[degrees] metamaterial differential phase
shifter as is shown in Figure 1(a).
The performance is defined by its insertion loss, return loss, and the deviation of the differential phase
In 2009, GlobeNet upgraded a segment of its network with Xtera's NXT 20 Gbps Differential Phase
Shift Key (DPSK) technology.
shift keying (DPSK) compares the phase of the present pulse with that of the previous one.
Xtera's contract with Global Crossing is to provide new capacity using the Xtera NXT next generation Submarine Line Terminal Equipment (SLTE) with 20 Gbit/s Differential Phase
Shift Technology (DPSK).
Xtera said its NXT Submarine Line Terminal Equipment (SLTE) with advanced 20Gb/s Differential Phase
Shift Keying (DPSK) technology has been selected for the Americas I North and Columbus 2b upgrade.
