This paper analyzes a model of a statistical multiplexer for packetized voice. The packet arrival stream from a single voice source is approximated by an interrupted Poisson process (IPP). The multiplexer is modeled by a single-server queue with general service time distribution, whose input is superposition of independent and identical IPPs. The steady-state probabilities of this queueing syst...

A full demonstration of the Fourier phase grating used as 4.7 THz local oscillator (LO) multiplexer for Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) is presented in this paper, including its design, modeling, tolerance analysis, and experimental characterizations angular intensity distributions among 2 × 4 output beams power efficiency. quantum cascade laser (QCL) to ...

This article presents a new compact multiplexer structure and its design approach, based on novel resonant manifold. Different from typical transmission-line-based manifold multiplexers, the proposed junction is formed of coupled resonators, so that also contributes to filtering poles selectivity in passbands. The all-resonator configuration achieves more footprint than conventional multiport n...

Quantum-dot cellular automata (QCA) technology is believed to be a good alternative CMOS technology. This nanoscale can provide platform for design and implementation of high performance power efficient logic circuits. However, the fabrication QCA circuits susceptible faults appearing in this form missing cells, additional rotated cells displaced cells. Over years, several solutions have been p...

In this paper, we consider a statistical multiplexer fed by heterogeneous ON and OFF sources. We provide closedform results on the tail behavior of the queue-length distribution for statistical multiplexers, where the tail behavior can be expressed in terms of traffic parameters such as the first and second moments of ON and OFF periods for individual sources. Since our results are of simple cl...

Real-time traffic processes, such as video, exhibit multiple time scale characteristics, as well as subexponential first and second order statistics. We present recent results on evaluating the asymptotic behavior of a network multiplexer that is loaded with such processes.

Estimating the cell loss probability in an ATM multi plexer is a key issue in network management and tra c control such as call admission control and bandwidth al location In this paper we derive a new approximation to estimate the total and individual cell loss probabilities in an ATM multiplexer fed by a superposition of hetero geneous on o sources with exponentially distributed on and o peri...
