This paper reports on the architectural, protocol, physical layer and integrated testbed demonstrations carried out by the DISCUS FP7 consortium in the area of accessmetro network convergence. Our architecture modelling results show the vast potential for cost and power savings that node consolidation can bring. The architecture however also recognises the limitations of long-reach transmission for low latency 5G services, and proposes how to address such shortcomings in future projects. The testbed results, which have been conducted end-to-end, across access-metro and core, and have targeted all the layers of the network, from the application down to the physical layer, show the practical feasibility of the concepts proposed in the project.

COMBINING BELIEF PROPAGATION AND SUCCESSIVE CANCELLATION LIST DECODING OF POLAR CODES ON A GPU PLATFORM

The decoding performance of polar codes strongly depends on the decoding algorithm used, while also the decoder throughput and its latency mainly depend on the decoding algorithm. In this work, we implement the powerful successive cancellation list (SCL) decoder on a GPU and identify the bottlenecks of this algorithm with ...

A New PRACH Transmission Scheme in Unlicensed Spectrum

  • Luo Z.
  • Meng Y.
  • Tao T.

For the unlicensed spectrum, the occupied bandwidth requirement is demanded by some regulations. The legacy scheme of Physical Random Access Channel (PRACH) for Long Term Evolution (LTE) cannot satisfy it. In this paper, we propose a novel PRACH transmission scheme to satisfy the requirement of unlicensed spectrum based on preamble ...

Mutual service processes in Euclidean spaces: existence and ergodicity

  • Baccelli F.
  • Mathieu F.
  • Norros I.

Consider a set of objects, abstracted to points of a spatially stationary point process in R-d, that deliver to each other a service at a rate depending on their distance. Assume that the points arrive as a Poisson process and leave when their service requirements have been fulfilled. We show ...
