  • Yin X.

A novel, low power, downstream clock and data recovery (CDR)- decimator architecture is proposed for next generation, energy efficient 10 Gb/s optical network units (ONUs). The architecture employs a new time division multiplexing (TDM) bit-interleaving downstream concept for passive optical networks (Bi-PON) allowing early decimation of the incoming data and ...

MIMO Communications using Trellis-based Channel Estimation

  • Chen Y.
  • Ten Brink S.

Motivated by the consideration of pilot overhead reduction for Multiple-Input Multiple-Output (MIMO) communications, we present a trellis-based joint channel and data estimation approach in this paper. The trellis tracking algorithm allows to estimate multiple channel coefficients in parallel while simultaneously performing a posteriori Probability (APP) detection of the transmitted bits. ...

Questions about Questions: Using Data from a Social Networking Application to Explore Enterprise Question and Answer Behavior

  • Burns M.
  • Friedman B.

We constantly ask questions in our search for new information, new knowledge. Paradoxically, although question asking is central to information transmission, we rarely consider the processes that we use to ask and answer questions. The recent deployment of an enterprise-wide social networking application in our company has provided an opportunity ...

Executing IJTAG: are vectors enough?

  • Goyal S.
  • Portolan M.
  • Van Treuren B.

This paper introduces a novel way of handling IJTAG operations where control is done at the state machine level rather than as vector level. After pointing out the shortcomings of traditional approaches, it presents TISA, a comprehensive solution that lets IJTAG express its full potential.

We present a new WDM-PON architecture based on amplified self-seeded RSOA creating an external cavity source. The cavity length can reach up to 45km of SMF. The transmission performances at 2.5Gb/s are demonstrated.

Dimensionierung des Ladeinfrastrukturbedarfs für Elektromobilität - Charging infrastructure dimensioning for Electric Mobility

  • Ballentin R.
  • Bross J.
  • Sund M.
  • Thielecke G.

Various factors require a fundamental change of our individual mobility behavior. These factors include among others the scarcity of fossil fuels like oil, environmental aspects and the increasing urbanization on a global scale. For this pur-pose different approaches will be examined. Electric mobility seems to be a serious alternative to ...

Uncovering Symmetries in Irregular Process Networks

  • Namjoshi K.
  • Trefler R.

Distributed protocols are often designed to run on arbitrary networks. The verification of such protocols is a challenge, as symmetry reduction arguments do not apply to irregular networks. On the other hand, the protocols often have correctness proofs which treat all nodes similarly, glossing over structural differences. In this work, ...

Using Social Influence to Predict Subscriber Churn

  • Doran D.
  • Kushnir D.
  • Mendiratta V.
  • Phadke C.
  • Uzunalioglu H.

The saturation of mobile phone markets has resulted in rising costs for operators to obtain new customers. These operators thus focus their energies on identifying users that will churn so they can be targeted for retention campaigns. Typical churn prediction algorithms identify churners based on service usage metrics, network performance ...
