Slow light fiber systems in microwave photonics

Luc Thévenaz, Sang Hoon Chin

Slow light systems are particularly attractive for analog signal processing, since their inherent limitation to a delay-bandwidth product of 1 is less critical for analog systems such as those used in microwave photonics. We present here the implementation ...

Workshop: Towards high capacity fibers for space and mode division multiplexed transmission

Hans Georg Limberger

The demand for capacity is growing exponentially with about 40-60% per year passing the installed network capacity. For the last two decades the transmission capacity per fiber has increased by more than three orders of magnitude: Single channel (wavelengt ...

Security Issues in Next Generation Mobile Networks: LTE and Femtocells

Jean-Pierre Hubaux, Murtuza Jadliwala, Igor Bilogrevic

Cellular mobile networks are used by more than 4 billion users worldwide. One effective way to meet the increasing demand for data rates is to deploy femtocells, which are low-power base stations that connect to the mobile operator through the subscriber's ...

Probabilistic Mining of Socio-Geographic Routines from Mobile Phone Data

Daniel Gatica-Perez, Katayoun Farrahi

There is relatively little work on the investigation of large-scale human data in terms of multimodality for human activity discovery. In this paper we suggest that human interaction data, or human proximity, obtained by mobile phone Bluetooth sensor data, ...

2010

Dynamic control of the speed of a light signal, based on stimulated Brillouin scattering in optical fibers, was theoretically studied and also experimentally demonstrated as the core object of this thesis. To date, slow light based on stimulated Brillouin ...

Effect of intelligent antennas on radio system planning and on mitigation

Juliane Iten Chaves Simoes

Smart antennas have been recently applied to improve the capacity and the performance of second generation wireless mobile communication systems. In general, smart antennas reduce the effects of multipath fading and improve the signal-to-noise-plus-interfe ...

EPFL2008

In spite of an immense interest from both the academic and the industrial communities, a practical multipleinput multiple-output (MIMO) transceiver architecture, capable of approaching channel capacity boundaries in realistic channel conditions remains lar ...

Life cycle assessment of mobile telephone networks, with focus on the end-of-life phase

Wolfram Scharnhorst

Mobile communication, in particular mobile telephony, is a service whose nonexistence nowadays is unimaginable. The ongoing, ever increasing penetration of mobile communication equipment, presently intensified by the transition from second generation1 to t ...

Effects of system and environment parameters on the performance of network-based mobile station position estimators

Cyril Botteron

This paper provides an asymptotic performance evaluation of network-based or multilateral positioning systems, where the times and/or angles of arrival of the signals traveling from a mobile station (MS) to a set of fixed stations (FSs) are used to estimat ...

Performance Analysis of Mobile Station Location Using Hybrid GNSS and Cellular Network Measurements

Pierre-André Farine, Cyril Botteron, Elham Firouzi

Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...
