We the study limitations to error-free transmission distance as set by noise accumulation and nonlinear pulse interactions in dispersion-managed N x 40-Gbit/s transmission systems with either distr

The nonlinear bit-error-rate (BER) performance of dense optical wavelength-division-multiplexed (WDM) Manhattan Street Networks with deflection routing was evaluated using an extendable semianalyti

This work was partly performed at Aston University during my PhD.

An introduction to the measure of information of a signal is presented. Challenges specific to calculating a nonlinear Shannon fiber capacity are highlighted.

New results for chalcogenide fibers based on As-Se-Ge where the optical bandgap is approximately twice the communication photon energies results in Kerr and Raman nonlinearities over 500 times the

This paper presents a new methodology for experimental charaterisation of distributed nonlinearity in microstrip circuits fabricated on commercial grade microwave laminate materials.

Products of passive intermodulation (PIM) generated by weak nonlinearities of passive circuits subjected to relatively high transmit power of multicarrier signals may cause strong interference in e

The performance of an automatic speech recognizer degrades when there exists an acoustic mismatch between the training and the testing conditions in the data.

Desoer gives an interesting analysis of distortion resulting from a nonlinearity of the form v + evm (m an odd integer) in a feedback loop.1 Sandbcrg considers virtually the same problem for nonlin

The standard model of speech assumes that speech is generated by a stochastic or periodic excitation, fed into a linear all-pole filter.
