The performance of a one-stage polarization-mode dispersion (PMD) compensator with different feedback signals is studied and compared with that of a pure first-order PMD compensator.
Two image subband coding methods are introduced as combinations of trellis-coded quantization (TCQ) with zerotree and stack-run coding, These TCQ-based image coding algorithms are compared, at low
Various advantages and drawbacks of the emerging technologies for RF power amplifiers like Si-VMOS, SIC-MESFET and GaN-HEMT are compared versus the established technology of Si-LDMOS.
As the rapid increase in mobile data traffics, radio-over-fiber(RoF) technology is one of the possible candidates for wireless signal distribution over fiber optic links.
Single-polarisation 160 Gbit/s OTDM transmission over 3 x 80 km dispersion-managed SLA fibre using DPSK and OOK modulation is reported.
A dry etch process for patterning SiO sub 2 / TiO sub 2 distributed Bragg reflectors (DBRs) for vertical cavity surface emitting lasers (VCSELs) was demonstrated.
4 different core networks - including EU and US - are studied for bit-rate adaptive opticalOFDM w.r.t. restoration.
Different possible implementations of WDM European network featuring elastic spectral efficiency are proposed and compared in terms of ratio of further regenerators they induce divided by the numbe
The density of states in two- and three-dimensional Penrose lattices with sites at vertices of rhombs were calculated in a one-orbital, tight-binding model.
A fundamental challenge for congestion control is the flow startup phase after the connection setup or after long idle periods.
