On time-bandwidth product of multi-soliton pulses

  • Aref V.
  • Bulow H.
  • Span A.
  • Ten Brink S.

Multi-soliton pulses are potential candidates for fiber optical transmission where the information is modulated and recovered in the so-called nonlinear Fourier domain. While this is an elegant technique to account for the channel nonlinearity, the obtained spectral efficiency, so far, is not competitive with the classic Nyquist-based schemes. In this ...

Communication-aware computing for edge processing

  • Avestimehr A.
  • Li S.
  • Maddah-Ali M.

We consider a mobile edge computing problem, in which mobile users offload their computation tasks to computing nodes (e.g., base stations) at the network edge. The edge nodes compute the requested functions and communicate the computed results to the users via wireless links. For this problem, we propose a Universal ...

We consider a cache network, where a single server is connected to multiple users via a shared bottleneck link. The server has a set of files, which can be cached by each user in a prefetching phase. In a following delivery phase, each user requests a file and the server ...

Characterizing the rate-memory tradeoff in cache networks within a factor of 2

  • Avestimehr A.
  • Maddah-Ali M.
  • Yu Q.

We consider a basic caching system, where a single server with a database of N files (e.g. movies) is connected to a set of K users through a shared bottleneck link. Each user has a local cache memory with a size of M files. The system operates in two phases: ...

Modern Software Defined Networking (SDN) applications rely on sophisticated packet processing. However, there is a mismatch between control plane requirements and data plane capabilities caused by increasing hardware heterogeneity. To overcome this challenge, we propose TableVisor, a proxy-layer for the OpenFlow control channel that enables the flexible and scalable abstraction ...

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

Chirp Management in Silicon-Graphene Electro Absorption Modulators

We study the frequency chirp properties of Graphene-on- Silicon electro-absorption modulators (EAMs). By experimentally measuring the chirp of a 100 um long single layer Graphene EAM, we show that the optoelectronic properties of Graphene induce a large positive linear chirp (up to 1.8 GHz) on the optical signal generated by ...

Wireless MIMO Base Station Near and Far Field Measurement Challenges

  • Moongilan D.

Wireless communication systems use Multiple Input Multiple Output-antenna techniques to increase coverage, data throughput and spectral efficiency. Often beam forming techniques are used to provide additional antenna gain relative to Single Input Single Output systems. Regulatory compliance radiated emissions tests for wireless devices are performed using a single measurement antenna ...
