SUMMARY: Recently codebook-excited linear prediction (CELP) coders, also known as stochastic coders, have been investigated for speech coding at low-to-medium bit rates.
Reports on a method and device that allow online measurement of PMD in a fiber link without data traffic interruption.
The study of low-temperature photoluminescence spectra of Ga47In53As as a function of excitation intensity reveals three distinct features: With decreasing excitation intensity the excitonic lin
It has been known that complete elimination of one of the sidebands in FM can be achieved by modulating the envelope by a signal related to the baseband modulation.
Multiple spot beam communication satellites offer the potential for greatly increasing the traffic handling capability relative to wide-area coverage systems, since the allocated spectral band can
Picosecond pulses are observed to exhibit large frequency shifts (-50 GHz) and spectral distortion on propagation through semiconductor laser optical amplifiers.
Spectral hole burning experiments based on high-resolution magneto-CW four-wave mixing in the phase conjugate geometry show that both the spectral and spatial diffusion of excitons is negligible in
A spectral-phase encoded OCDMA system is demonstrated in a back-to-back optic fiber link.
Until now static spectrum management has ensured that DSL lines in the same cable are spectrally compatible under worst-case crosstalk conditions.
We report on the generation and the transmission of 1-Tb/s superchannels for long-haul optical systems.
