Optimal fronthaul capacity allocation and training for joint uplink receiver in C-RAN

  • Boviz D.
  • Sheng Yang

In Cloud Radio Access Networks (C-RAN) one of the main challenges is accurate data transfer on limited capacity fronthaul links between Remote Radio Heads (RRHs) and the central processing unit. Particularly in large-band and multiantenna transmissions, fronthaul capacity can be a limiting factor. In this paper we study the impact ...

  • Lopez-Perez D.
  • Meryem Simseky

The handover process is one of the most critical functions in a cellular network, and is in charge of maintaining seamless connectivity of user equipments (UEs) across multiple cells. It is usually based on signal measurements from the neighboring base stations (BSs), and it is adversely affected by the time ...

Spectral-Phase Encoded Optical CDMA Using Coherent Self-Homodyne Detection

  • Kaneda N.
  • Lee S.
  • Sakib M.
  • Wu M.

A spectral-phase encoded OCDMA system is demonstrated in a back-to-back optic fiber link. Code-division discrimination is successfully achieved using a self-homodyne technique at 500Mb/s channel data rate with a BER of 8.9x10-5 for two simultaneous users. OCIS codes: (060.1660) Coherent communications; (140.4050) Mode-locked lasers; (060.2330) Fiber optics communications.

Discrete-multitone modulation for short distance 100 Gbit/s optical links

  • Pilori D.

The commercially available 100 Gbit/s optical channel employs coherent modulation and demodulation allowing transmission over long distances, up to thousands of kilometers, but for short distances the cost of a coherent receiver can be overkill. In literature there are several techniques, based on advanced different digital modulation schemes, that reduce ...

A novel perturbative-based algorithm to jointly compensate intra and inter-channel nonlinearities of the subcarriers of a super-channel is introduced for the first time, and demonstrated in a transmission experiment of a quad-carrier 30.75 GBd PDM-16QAM over transoceanic distances.

This paper presents a theoretical comparison between traditional non-return-to-zero, PAM4 and duobinary signaling as ways to achieve high serial data rates over copper. From this analysis, the channels for which duobinary is able to provide the optimal solution are discussed. A practical proof of the merits of duobinary is given ...

RSSI localization with Gaussian Processes and Tracking

  • Claussen H.
  • Dashti M.

  • Yiu S.

Location Fingerprinting (LF) is a promising localization technique that enables many commercial and emergency location-based services (LBS). While significant efforts have been invested in enhancing LF using advanced machine learning methods, the configuration effort required to deploy a LF system remains a significant issue. In this paper a practical LF ...

Motivated by the needs of health monitoring at home (or a senior center) using a sensor network system, we study the problem of how to place the relay nodes so that the data collection and localization requirements of the monitoring system can be satisfied. By exploiting the inherent nature of ...

Chapter 9 (METIS Book) Multi-node Coordination

  • Aziz D.
  • Baracca P.
  • Fantini Roberto
  • Thiele L.
  • Zirwas W.

Performance in a wireless network strongly depends on user position in the cell, with users in the cell border typically experiencing much lower throughputs than those nearer to the transmitting base station. This is mainly due to the presence of inter cell interference, generated by concurrent transmissions in other cells. ...

Limits of nonlinear compensation in massive WDM systems

  • Dar R.
  • Winzer P.

We examine the maximal achievable gains of digital back-propagation (BP) in typical modern WDM systems. We show that in a fully loaded WDM environment, the potential benefit of single-channel BP is limited to ~ 0.5dB improvement in the maximal SNR, and about 1dB and 1.2dB in the case of 3 ...

H2C: a Hierarchical Two-layer Caching Design for Networked System

  • Gallo M.
  • Lorenzo Saino
  • Perino D.

Packet-level caching is becoming increasingly important as it is exploited by several network applications today, and proposed as basic building block of future Internet architectures. This demands for high-speed caching designs that leverage heterogeneous storage technologies to scale the storage space up to TBs, and off-the-shelf general purpose hardware to ...

Scaling Laws for Maximum Coloring of Sparse Random Geometric Graphs

  • Borst S.
  • Bradonjic M.

We examine maximum vertex coloring of random geometric graphs, in an arbitrary but fixed dimension, with a constant number of colors. Since this problem is neither scale-invariant nor smooth, the usual methodology to obtain limit laws cannot be applied. We therefore leverage different concepts based on subadditivity to establish convergence ...

The continuous growth of demand for wireless connectivity has turned bandwidth into a scarce resource that should be carefully managed. A common solution is to assign disjoint portions of the bandwidth to different users, but the portion size decreases as the number of users grows. An alternative solution is to ...

In this paper, a new approach to non-orthogonal multiuser downlink transmission, referred to as modulo multilevel codes based multiuser superposition transmissions (MMC-MUST), is proposed, which addresses the main issues of existing solutions by 1) overcoming the challenge faced by NOMA when users have the similar channel conditions; 2) adopting the ...

Nonlinear analysis of a two-degree-of-freedom energy harvester

  • Frizzell R.

In recent years the use of Wireless Sensor Networks (WSNs) has increased rapidly, enabled by the development of small and ultra-low power electronics. The majority of these sensors are battery powered, and this can lead to high maintenance costs when batteries have to be replaced. A practical solution to power ...
