We describe an algorithm for sub-carrier and power allocation that achieves out-of-cell interference avoidance through dynamic fractional frequency reuse (FFR) in downlink of cellular systems based

Social networks offer users new means of accessing information, essentially relying on ``social filtering{''}, i.e. propagation and filtering of information by social contacts.

Fourth generation cellular systems are currently being developed and deployed. Long Term Evolution (LTE) is one such 4G system and is an evolution of the 3GPP UMTS Standard [1][8].

Self-Organizing Networks (SON) is a common term for mobile network automation, critical to the cost-efficient deployment, operation and maintenance of mobile networks.

We propose a self-organizing sleep-wake sensor system that is scalable, easily implemented, and energy conserving.

A method for making arrays of polarization maintaining fibers is proposed and demonstrated. Flattened fiber which is externally keyed to the polarization axes is used.

A Minkowski disk is the unit ball of a 2-dimensional Minkowski space, i.e., a compact convex body symmetric around 0 in R sup 2 which has nonempty interior.

We have investigated experimentally the influence of stimulated Raman scattering, under conditions of pulse walk-off, on the propagation of mode-locked 1.06microns pulses in single-mode, polarizati

Full-duplex 10Gb/s transmission is demonstrated on a single wavelength with RSOA-based ONUs, whose amplified spontaneous emission establishes a pump for remote amplification to overcome the loss bu

We report here for the first time the demonstration of self- pumped phase conjugation in photoefractive semiconductors using 1.32micron light.
