The use of Erlang's probability equation for determining the number of circuits required in exchange systems requires a knowledge of the average busy-hour traffic, and this must be determined exper

In order to achieve high critical currents, the bulk high T sub c superconductors have to be processed for i) near perfect grain alignment to overcome the weak-link problem and ii) increased dens

The efficient transportation of real-time Variable Bit Rate (VBR) video traffic in the high-speed networks has been an area of active research.

In this paper, we report on some transmitter and optical fiber technologies for 10 Gb/s speed datacom systems.

With advanced modulation, 100-Gb/s systems over 100s of kilometers based on directly-modulated single-model VCSELs are achieved using coherent detection, and an 115-Gb/s line-rate short-reach syste

We relate the optical beam waist of a vertical-cavity surface-emitting laser (VCSEL) to a measurement of the transverse mode splitting found in the device's optical output spectra and to a measurem

Over the previous decades, successive DSL technologies have increased the transmission speeds over the telephone access network from 33.6 Kbit/s for analog modems to about 8 Mbit/s with ADSL.

The vector modulation interaction is a degenerate four-wave mixing process in which a strong pump drives weak signal and idler sidebands, each of which has two polarization components.

A key element in the eventual application of the articulatory approach to low bit-rate coding is the ability to derive model parameters from the speech signal.

The problem of improving the noise covariance matrix estimation with limited training data to improve the performance of the vector Viterbi algorithm (VVA) in the space-time equalizer for mobile co
