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.
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 […]
A digital coherent super-receiver enables the reception and demodulation of a 7×10GBd DP-64QAM Nyquist spaced super-channel.Multi-channel DBP provides a 100% improvement in reach from 640km to 1280km of SSMF, with an ISD of 9.15b/s/Hz.
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 […]
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, […]
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 […]
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 […]
