We review the concept of probabilistic constellation shaping (PCS) and of its applicability for high-capacity autonomous networks.
An integrated telephone network is defined as one in which both speech transmission and switching are done with the same type of modulation.
For Part I see abstract 1963B13777.
For Parts I and II see abstracts 1963B13778. Possible methods of connecting subscriber lines to a pulse-code highway are discussed.
The Fourier transform method has long been used to characterize linear systems and to identify the frequency content of waveforms.
We demonstrate that spectral filtering of a self phase modulation broadened bit stream may be used to measure residual dispersion.
Describes a system in which a second channel is superposed on extra light phantom circuits having a cut-off frequency 7000 ~.
The complexity of distributed computer systems has been growing steadily over the past several years.
Analysis by software reliability modeling of data taken during testing of a software system was used to predict system quality during field use.
Previous articles [see Abstract 1938B01678] have described early experimental work in the application of styrenation to joints and terminations for h.t. cables.
