ABSTRACT:
Massive connectivity is a key requirement for future 5G wireless access. This talk considers a massive device communications scenario in which a large number of devices need to connect to a base-station, but user traffic is sporadic so that at any given coherence time only a subset of users are active. For such a system, user activity detection and channel estimation are key issues. This talk first provides an information theoretical analysis for massive connectivity by illustrating how the cost of user identification and channel estimation affects the achievable degree-of-freedom. Next, we present a two-phase framework in which compressed sensing techniques are used in the first phase to identify the devices and their channels, while data transmission takes place in the second phase. We propose the use of approximate message passing (AMP) for device identification and show that state evolution can be used to analytically characterize the missed detection and false alarm probabilities in AMP. This talk further considers the massive connectivity problem in the massive MIMO regime. We analytically show that massive MIMO can significantly enhance user activity detection, but the non-orthogonality of pilot sequences can nevertheless introduce significant channel estimation error, hence limiting the overall rate. We quantify this effect and characterize the optimal pilot length for massive uncoordinated device access.

ABSTRACT:

Deterministic Ethernet aims at filling the gap left by the IEEE802.1Q standard to proprietary solutions (e.g. CAN buses), regarding soft and hard real-time applications. Ethernet was first thought to be probabilistic by nature in order to provide reliability and fairness for accessing to the medium. However, the unpredictable delivery of Ethernet frames may lead to unwanted loss, delay and jitter in streams, with potentially disastrous consequences on life-critical applications – one cannot accept a smart car controller freezing, waiting for a delayed sample coming from a sensor.

In this presentation, we will discuss Deterministic Ethernet, and Time-Sensitive Networking and show how with an accurate Timing and Synchronization protocol (IEEE802.1AS), a Time-Aware scheduler (IEEE802.1Qbv) can ensure the tight time-delivery of frames. Also, we will talk about drafts and future concepts of TSN, such as the frame preemption (IEEE802.1Qbu). Practical use cases and a review of the state-of-the-art tools will be provided to achieve determinism in an existing network.

BIOGRAPHY OF THE PRESENTER:

Dr. Guillaume Mantelet has been working in Embedded Software Engineering at Iders – a GE Transportation company, since 2015. He received his M.Sc. in Telecommunications and Network Engineering (2007) and Ph.D in Electrical Engineering (2012) at Ecole de Technologie Superieure in Montreal. Before joining Iders, he worked as a Software Quality Assurance Specialist at Accedian Networks (2012).

Dr. Mantelet’s core expertise is “layer 2” oriented, and includes the establishment of end-to-end paths in optical transmission lines, and the definition of a control plane, Carrier Ethernet and more specifically, concepts touching the Quality of Service in Ethernet networks, and more recently Deterministic Ethernet. Starting with a scientific training, he could leverage his knowledge by developing tools in embedded projects.

Abstract of the Presentation: As computational methods for solving Maxwell’s equations become mature, the time has come to tackle much more challenging multiphysics problems, which have a great range of applications in sciences and technologies. In this presentation, we will use four examples to illustrate the nature and modeling of multiphysics problems. The first example concerns the heat problem in integrated circuits due to electromagnetic dissipated power, which requires an electrical-thermal co-simulation. The second example considers modeling of monolithic microwave integrated circuits, which consist of both distributive and lumped circuit components. The third is the simulation of vacuum electronic devices using the particle-in-cell method, which solves Maxwell’s equations and particle kinetic equation, and the fourth example simulates the air and dielectric breakdown in high-power microwave devices by coupling electromagnetic modeling with various plasma models. With these examples, we will discuss the methodologies and some of the challenges and potential solutions in multiphysics modeling.
