FLEXIBLE 50 GBPS PON BASED ON CAP-4 AND PAM-4 WITH USER INTERLEAVING

In this paper we propose a flexible 50G PON based on CAP (carrier less amplitude phase) modulation and compare this with our user interleaving PAM-4 scheme at 50G as well.

Stability and performance bounds in cyclic networks using newtork calculus

With the development of real-time systems and of new wire less communication technologies having strong requirements on latencies and reliability, there is a need to compute deterministic performance bounds in networks. This paper focuses on the performance guarantees and stability conditions of networks with cyclic dependencies in the net work ...

Own Linux for Raspberry Pi

Tutorial how to roll own Linux distribution. As an example platform Raspberry Pi Zero was choose. Article starts from configuring cross compiler. Then compilation of U-Boot and Kernel is described.

Model-free Training of End-to-end Communication Systems

The idea of end-to-end learning of communication systems through neural network-based autoencoders has the shortcoming that it requires a differentiable channel model. We present in this paper a novel learning algorithm which alleviates this problem. The algorithm enables training of systems with an unknown channel model or with non-differentiable components. ...

Nicotine matters in predicting subsequent smoking after e-cigarette experimentation: A longitudinal study among Finnish adolescents

© 2019 The Authors Background: Several studies indicate an association between e-cigarette use and subsequent smoking among youth. However, most previous studies lack measures of the nicotine content of e-liquid and have not usually measured regular smoking. Methods: We tested the association between e-cigarette use, with and without nicotine, and ...

Fiber To The Tap: Pushing Coaxial Cable To Its Limit

We explore the potential of a future cable access technology that pushes the capacity of the coaxial cable network to its limits. We will show that it is possible to achieve symmetric data rates of multiple tens of gigabit per second, using the same coaxial drop cables in use today ...

High Speed Copper and Coaxial Broadband

of deeper fiber is facilitated by the ability to leverage the remaining copper drop for providing ubiquitous gigabit access to everyone within the service area. In contrast, fiber roll-outs that don't leverage the copper network are regional - as region-by-region is upgraded to full fiber, the remaining regions are under-served. ...

Protecting photonic quantum states using topology

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

G.mgfast - a New Generation of Copper Broadband Access

The draft ITU-T standard for MGfast technology transmission of up to 10 Gbps over copper is scheduled for completion July 2019. In addition to providing multi-gigabit-per-second access to the customer, MGfast will provide sub-millisecond latency, full-duplex transmission, enhanced support of multiple quality-of-service grades, and point-to-multipoint operation.

Digital Signal Processing in Optical Access Systems

Abstract: We analyzed the introduction of DSP in optical access. We reviewed the specific requirements of PON and compared performance and feasibility of DSP-based PON with solutions for cost-effectively increasing the bit-rate in PON without DSP

Supramolecular Self-Assembly and Organization of Collagen at Solid/Liquid Interface: Effect of Spheroid- and Rod-Shaped TiO<inf>2</inf> Nanocrystals

KGaA, Weinheim The adsorption behavior of collagen on solid surfaces is a process that determines the role of this protein to mediate cell?material interaction. Herein, the mechanism of self-assembly and organization of collagen on a model substrate is investigated in the presence of TiO2 nanoparticles. In solution, results show that ...

RAn resource usage prediction for a 5G slice broker

Network slicing will allow 5G network operators to oer a diverse set of services over a shared physical infrastructure. We focus on supporting the operation of the Radio Access Network (RAN) slice broker, which maps slice requirements into allocation of Physical Resource Blocks (PRBs). We rst develop a new metric, ...

Future Millimeter-Wave Indoor Systems: A Blueprint for Joint Communication and Sensing

© 1970-2012 IEEE. Millimeter-wave (mm-wave) technology is emerging as a de facto enabler for next-generation high-rate communications. We propose that a unified mm-wave system for combined communication and robust sensing will turbocharge the capabilities of application domains from in-home digital health to new possibilities for building analytics.

Liability of Internet Service Providers - A Review Study from the European Perspective

Internet has revolutionized peoples lives by offering a medium to share and receive abundant information. However, this resource hub has become a harbour for the infringement of IP material. Although the sole responsibility lies on the internet user; some degree of liability shouldered on the internet service providers cannot be ...

Latency control in Deterministic and Dynamic Networks

We present Deterministic Dynamic Network as a solution for 5G Edge Cloud and show how we control latency to ensure end-to-end deterministic performance of only tens of microseconds latency and tens of nanoseconds jitter per-application

Run-time Performance Monitoring, Verification, and Healing of End-to-End SDN Services

Softwarization enables tremendous flexibility for networks as the use of software-defined networking (SDN) and programmable data planes (e.g. P4) together support dynamic reconfiguration of networks in real-time, in response to network conditions and new service requests. However, as the topologies and characteristics of the dynamically reconfigured networks are not known ...

Secure Application-Oriented Network Micro-Slicing

Future networks rely on network slices to flexibly adapt the network connectivity. We have introduced micro-slices that allow end-devices to be dynamically inter-connected or isolated from other end-devices according to their collaboration needs. In this demo we illustrate the use of such micro-slices in the context of a show happening ...
