DyMo: Dynamic Monitoring of Large-Scale LTE-Multicast Systems

IEEE LTE evolved Multimedia Broadcast/Multicast Service (eMBMS) is an attractive solution for video delivery to very large groups in crowded venues. However, the deployment and management of eMBMS systems are challenging, due to the lack of real-time feedback from the user equipments (UEs). Therefore, we present the Dynamic Monitoring (DyMo) ...

Will Serverless Computing Revolutionize NFV?

Communication networks need to be both adaptive and scalable. The last few years have seen an explosive growth of software-defined networking (SDN) and network function virtualization (NFV) to address this need. Both technologies help enable networking software to be decoupled from the hardware so that software functionality is no longer ...

Next Generation Platform as a Service: Toward Virtualized DVB-RCS2 Decoding System

Platform-as-a-Service (PaaS) cloud computing services have emerged in the last few years, offering an abstraction framework to enable the development, execution, and management of applications, which is de-coupled from complex infrastructure considerations. The next generation of PaaS solutions (NGPaaS) will have to address more stringent performance requirements compared to traditional ...

A 5GS/s 12b 158.6mW Passive-Sampling 8x-Interleaved Hybrid ADC With 9.4 ENOB and 160.5dB FoM in 28nm CMOS

Emerging 5G communication systems require ADCs to directly digitize wide bandwidth (BW) signals with high spectral purity at low power consumption. Current state-of-the-art solutions include mainly time-interleaved (TI) pipelined or pipelined-SAR architectures, enhanced by digital calibration. To ensure a sufficiently high input BW, all these designs employ a front-end buffer. ...

On Tracking the Physicality of Wi-Fi: A Subspace Approach

Wi-Fi channel state information (CSI) has emerged as a plausible modality for sensing different human activities as a function of modulations in the wireless signal that travels between wireless devices. Until now, most research has taken a statistical approach and/or purpose-built inference pipeline. Although interesting, these approaches struggle to sustain ...

Probabilistic Constellation Shaping For Optical Fiber Communications

We review probabilistic constellation shaping (PCS), which has been a key enabler for several recent record-setting optical fiber communications experiments and has been commercialized in Nokia PSE-3s coherent optical transponders. PCS provides both fine-grained rate adaptability and energy efficiency (sensitivity) gains. We discuss the reasons for the fundamentally better performance ...

Noise Analysis of Zero-Forcing Nonlinear Equalizers for Coherent WDM Systems

We explore the fundamental limits on the achievable information rate of fiber-optic coherent transmission systems equipped with ideal zero-forcing nonlinear equalizer (ZFNLE). In the absence of amplifier noise, the ZFNLE forces the nonlinear signal-signal distortions to zero. If amplifier noise is included in the analysis, the equalization performance is severely ...

Survey of Performance Acceleration Techniques for Network Function Virtualization

The ongoing network softwarization trend holds the promise to revolutionize network infrastructures by making them more flexible, reconfigurable, portable, and more adaptive than ever. Still, the migration from hard-coded/hardwired network functions towards their software-programmable counterparts comes along with the need for tailored optimizations and acceleration techniques, so as to avoid, ...

Going down dangerous paths? (An editorial)

At the end of my 6-year tenure as the Editor-in-Chief of the IEEE/OSA Journal of lightwave technology, I would like to take the opportunity to not only reflect on this very special journal that has served our photonics community for the past 35 years, but more generally on the state ...

Annotate: Organizing Unstructured Contents Via Topic Labels

This is a presentation for the publication that has been already cleared for external release. With the advent of Big Data paradigm, filtering, retrieval, and linking of unstructured multi-modal data has become a necessity. Assigning topic labels to contents, that accurately capture the meaning and contextual information, is a fundamental ...

Deadline Constrained Traffic Handling under Average Power Constraints

Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, we consider delay sensitivity in the form of strict deadlines on packet arriving in a transmission queue. Packets missing the deadline while in the ...

A Secure End-to-End Cloud Computing Solution for Emergency Management via UAVs

To properly determine the severity of an emergency and provide a quick response, information has to be gathered, confirmed, and analyzed. Artificial intelligence assisted UAV can provide a unique perspective and review extensive information for an incident. However, their limited computing capacity and battery duration raise the challenge to compute-intensive ...
