This paper presents a voltage control scheme for coordinating reactive power reserves, inspired by the concept of multi-agent system. Similar to an agent, the proposed controller takes on assigned tasks itself and contacts neighbors for support when needed. The control structure incorporates not only controllable VAr sources but also switched capacitor banks, resulting in increased […]
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.
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 […]
In this paper we study the circuit design implications of Ge vs. Si PMOS FinFETs at the 10 and 7nm nodes, using TCAD calibrated statistical compact models and the ARM predictive benchmarking flow. The ARM predictive flow incorporates advanced-node-relevant layouts, design rules, parasitic RC extraction and wire-loading. We present the first comprehensive simulation study evaluating […]
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 […]
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), […]
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 […]
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.
Amplify-and-forward (AF) relaying protocols are an important class of cooperative relaying protocols. Non-orthogonal AF (NAF) relaying, where the source sends new information while the relay forwards previously transmitted information, can achieve higher transmission rates than orthogonal relaying, where the source and relay do not transmit simultaneously. However, all the transmitted symbols in NAF relaying do […]
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 […]
