that four talking circuits had been added to one pair of wires already in use for telephone and telegraph communication and were being used commercially between Pittsburgh and Baltimore for providi

In a previous paper by the author [see Abstract 1933B02276] a new unit was described for the rating of the overall performance of a telephone circuit taking into account the various factors which a

HE purpose of this paper is to outline the practical considerations involved in the use of the transmission unit (abbreviated TU), which was recently adopted by the Bell System to replace the mile

We review single-carrier 400 Gb/s transponder design and experiments.

In the past few years we have seen the proliferation of mm-Wave & sub-6GHz communication radios due to the global effort to make ultra-high capacity 5G a reality.

In the presentation I will focus on practical consequences affecting system and entity when applying certain solutions as a part of microservice architecture, each design brings benefits, limitatio

For transmission systems at 10 Gb/s and beyond, polarization-mode dispersion (PMD) is one of the limiting factors.

It is shown that simple variations on rate-compatible error correcting codes are able to achieve cooperative coding gains for the half-duplex relay channel without the complexity of capacity achiev

Data mining algorithms utilize search techniques to explore hidden patterns and correlations in the data, which otherwise require a tremendous amount of human time to explore.

It is commonly known that in the realization of high-order active filters, properly designed multiple-loop-feedback topologies offer far superior sensitivity performance than the approach of cascad
