This paper introduces and evaluates a hybrid OBS/OCS switch for Quality of Service (QoS) differentiation in next-generation all-optical transport networks. Depending on their QoS requirements, incoming IP packets are ...

This paper considers a Frequency Hopped Multilevel Frequency Shif Keying (FH-MFSK) spread spectrum communication system applied to mobile radio-telephony. We present a mobile-to-base transmission model that allows to study ...

This paper deals with the performances of a coherent optical fiber transmission link with linear optical amplifiers chains in which identical sections of attenuating fiber alternate with identical amplifiers. The overall ...

The main weakness of Elastic Optical Networks (EON) stems from spectrum fragmentation. An analysis of periodic defragmentation in EONs under dynamic traffic conditions is carried out. The effects of different defragmentation ...

En esta comunicación presentamos una modulación en banda ensanchada FH-MFSK (Frequency Hopping - Multiple Frequency Shift Keying) apta para utilizarse en comunicaciones militares móviles como técnica de múltiple acceso. ...

We devised a probabilistic model to compute the number of used wavelengths in every link of a transparent optical network. Based on this model, a novel approach for impairments-aware RWA algorithm is proposed and evaluated.

This work is focused on the characterization of the traffic allocated in Elastic Optical backbone networks when different dynamic traffic profiles are generated. Extensive simulations are done to statistically model the ...

This paper concers the design and present results of a CPFSK optical receiver for a 2.5 Gbit/s coherent system operating at 1.55 ¡.¡m. The received CPFSK modulated signal is converted into the electrical domain by means ...

A delay in homodyne PSK receivers with decision-driven Phase Locked-Loop is needed to equalize the transit time in the arms. This work shows a study about the effect of this delay over the phase variance and the receiver ...
