This paper presents a new nonnegative dictionary learning method, to decompose an input data matrix into a dictionary of nonnegative atoms, and a representation matrix with a strict l0-sparsity con
K24A system was developed by the International Telephone and Telegraph Laboratories for the exchange junction circuits, 5 to 20 miles long, with a total attenuation of 200 dB at 500 kc/s.
Telecommunication payloads for multimedia missions demand a large diversity of Ka-band products, particularly in term of frequency conversions (down-conversion from Ka to L-band and opposite up-con
A new design and realisation of high performance micromachined millimetre wave circuits on silicon is presented.
The design of a coplanar low-noise amplifier (LNA) is presented in this paper.
Low noise amplifiers in receivers are usually addressed by III-V (narrow bandgap) technologies: but when the receivers are subject to EM exposure or jamming, the need for protection devices before
We present recent developments of multiple-beam antennas (MBA) in Ka-band. A multi-feed Gregorian antenna for a gateway link is described.
Apache Kafka and RabbitMQ are two popular publish/subscribe implementations that can be used when a multitude of data streams need to be connected between a set of producers and a set of con- sumer
Projections of message circuit usage (as measured in hundred call seconds or ccs), from which message circuit requirements (trunks) are developed, and special services* circuit demand are fundament
In this paper we consider the issue of source clock frequency recovery in packet networks and propose a new adaptive clock method based on the Kalman filter (KF) with low-pass prefiltering-KALP (Ka
