70 nm seamless band transmission of 17.3 Tb/s over 40×100km of fiber using complementary Raman/EDFA

We demonstrated 70nm seamless band transmission of 173×128Gb/s QPSK signals over 40×100km of TeraWave™ fiber. The complementary Raman/EDFAs and wide-band single-stage discrete Raman amplifiers were used to achieve this 17.3Tb/s capacity ultra-wide single-band transmission.

Magnetic interaction and electronic transport in La0.4Bi0.6Mn0.5Ti0.5O3manganite

In recent years perovskite type manganites having general formula ABO3 have attracted significant deliberation because of their importance both for potential magneto-electronic applications and fundamental research in condensed matter physics. The properties of these materials such as magnetoresistance, metal-insulator transition, charge, magnetic ordering, etc., have attracted significant attention [1]. The substitution of divalent or other trivalent […]

From Demand Response in Smart Grid Toward Integrated Demand Response in Smart Energy Hub

The proliferation of technologies such as combine heat and power systems has accelerated the integration of energy resources in energy hubs. Besides, the advances in smart grid technologies motivate the electricity utility companies toward developing demand response (DR) programs to influence the electricity usage behavior of the customers. In this paper, we modify the conventional […]

Downlink interference penalty algorithm for power control, scheduling, and user association

Managing inter-cell interference is one of the main challenges in current and next generation wireless systems that aggressively reuse the frequency. Cooperation between interfering cells has been sought to mitigate interference. In this paper, we address the problem of jointly optimizing the transmit powers, user scheduling, and user association in a cellular network to maximize the weighted […]

Coverage enhancement techniques for machine-to-machine communications over LTE

The tremendous growth of machine-tomachine (M2M) applications has been a great attractor to cellularnetwork operators to provide machine-type communication services. One of the important challenges for cellular systems supporting M2M terminals is coverage, because terminals can be located in spaces in buildings and structures suffering from significant penetration losses. Since these terminals are also often stationary, […]

HomePlug green PHY for the LVDC PLC concept: Applicability study

It has been shown that high-frequency (HF) band power line communication (PLC), that is, the HomePlug 1.0 specification, is feasible for a low-voltage direct current (LVDC) smart grid (SG) system, where power electronics and low-voltage DC are applied to the electricity distribution. In this paper, the applicability of the latest HomePlug specification, Green PHY (GP), […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications

Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared […]

Network coding based mechanism to provide reliable multimedia content distribution in harsh environments

Multimedia services distribution is very dependent on the quality of the communications link. Due to the nature of the related services, these are usually very sensitive to packet loss, delay and jitter, and hence service quality is immediately worsen in harsh scenarios. This paper proposes an OSI-Layer2 cooperative link layer scheme (known as GalaReS) that […]

Silicon photonics and FDMA-PON: Insights from the EU FP7 FABULOUS project

The FABULOUS EU project aims at demonstrating the effectiveness of a self-coherent reflective FDMA WDM PON architecture, achieving record transmission performances and demonstrating an ONU as a silicon-photonics PIC with unprecedented level of integration.

Efficient MAC protocols optimization for future high density WLANS

Recently, the High Efficiency WLAN or simply HEW study group was created within IEEE 802.11 working group. This study group considers the improvement of spectrum efficiency to enhance the system’s area throughput in high density scenarios. Subsequently, this led to the creation of a new task group called 802.11ax, which is expected to deliver the […]
