Inter-Channel Crosstalk Cancellation for WDM Time-Frequency Packing System

  • Aref V.
  • Buchali F.
  • Buelow H.
  • Dischler R.
  • Hu Q.
  • Idler W.
  • Schmalen L.

We apply a joint DSP for inter-channel crosstalk compensation in WDM time-frequency packing systems. The OSNR penalty is improved at most by 2 dB with the inter-channel crosstalk cancellation.

Pulse Shape Dependence of Stochastic Nonlinear Interference in Dispersion Managed 100G Systems

  • Bigo S.
  • Ghazisaeidi A.
  • Rossi N.

We quantify the stochastic nature of the nonlinear interference in dispersion managed links for different pulse shapes. We show that the nonlinear interference can be modeled as a Gaussian random variable for each investigated pulse shape.

Reception of 180-GBaud Nyquist Shaped Optical QPSK Signals Generated from a 240-GSa/s, 100-GHz Analog Bandwidth DAC

  • Chen X.
  • Khanna A.
  • Pupakalis P.
  • Sethumadhavan C.
  • Steffan A.
  • Umbach A.
  • Winzer P.

We demonstrate reception of 180-Gbaud QPSK generated from a 240-GSa/s, 100-GHz bandwidth digital-to-analog converter (DAC). Using a novel time-multiplexed coherent detection scheme, we achieve an 8-dB implementation penalty for the 300-Gb/s single-wavelength and single-polarization system.

Enabling ICN in IP networks via DNS Extensions: A Measurement Study

  • Hilt V.
  • Satzke K.

ICN promises benefits to users and service providers along several dimensions, including lower response time, nearest-replica routing, intrinsic content integrity without external network-level indicators, location-independent naming and improved support for mobility. However, these benefits come at non-trivial cost as many ICN proposals call for adding significant complexity to the network. ...

We demonstrate the all-electronic generation of 180-GBaud Nyquist shaped pulse amplitude modulated (PAM) signals with 99-GHz RF bandwidth using digital bandwidth interleaving (DBI).

Future Cognitive Mobile Networks : Connecting Management and Orchestration

  • Gruber M.

The goals when running a mobile network have remained the same over the years, namely reducing CAPEX/OPEX by decreasing the necessary level of manual intervention and increasing the network performance. However, the complexity has dramatically increased: 5G networks will have to be able to deal with dynamic slice management and ...

On Bayesian high-dimensional compressed sensing

  • Jalali S.
  • Maleki A.

In this paper, the problem of Bayesian compressed sensing is studied. Given the distribution of the source, and under-determined linear measurements of the source vector, a new recovery algorithm proposed that asymptotically achieves the optimal performance.

Go-Index: Applying supply networks principles as Internet robustness metrics

  • Bachmann I.
  • Bustos-Jimenez J.
  • Morales F.
  • Silva A.

Whether as telecommunications or power systems, networks are very important in everyday life. Maintaining these networks properly functional and connected, even under attacks or failures, is of special concern. This topic has been previously studied with a whole network robustness perspective. With this perspective, whenever a node is removed the ...

Opinion Manipulation in Social Networks

  • Silva A.

In this work, we are interested in finding the most efficient use of a budget to promote an opinion by paying agents within a group to supplant their true opinions. We model opinions as continuous scalars ranging from 0 to 1 with 1 representing extremely positive opinion. We focus on ...
