Title: Optimization of DSP-Based Optical Communication Links Beyond 100Gbps

Speaker: Tony Chan Carusone                

Professor, University of Toronto

Chief Technology Officer, Alphawave IP Group

Date: Monday, August 8th

Time: 2pm

Location: Walter Light Hall Rm 302, Queen’s University

Abstract:

Progress in computation and communication is increasingly bottlenecked by integrated circuit I/O. Previously reserved for communication over 100’s of kilometres, today optical links are widely viewed as the primary solution for chip-to-chip links above 100 Gbps and up to 1 km.  Meanwhile, CMOS technology scaling has led us toward integrated circuit transceivers that are, essentially, complete modems: thin but critical analog front-end circuits and a large custom DSP.  This presentation will describe how to co-design of DSP transceivers with a thin but critical analog front-end and the associated optical components to create optical links serving future datacentre communication needs.  As an example, a 4-PAM CMOS linear TIA designed in a FinFET technology consuming less than 50 mW and co-packaged alongside photodiodes is presented. The circuits and packaging are co-designed to maximize the passive front-end BW. Experimental results confirm the integrated optical fibre receiver operates up to 160-Gb/s using a single wavelength with a suitable DSP.

UNCERTAINTY ASSESSMENT FOR DEEP NETWORKS: MAKING AUTONOMOUS DRIVING PERCEPTION AWARE OF ITS OWN LIMITATIONS

 

Date:  Wednesday November 20th, 2019.

Time:  12:30 – 1:30 PM

Location: Mitchell Hall, Room 395, Queen’s University 

Speaker:  Prof. Steve Waslander, University of Toronto Institute for Aerospace Studies (UTIAS). Director, Toronto Robotics and Artificial Intelligence Laboratory (TRAILab).

Light Refreshments: 1:30 – 2:00PM, Mitchell Hall, Room 395, Queen’s University

 

Abstract

Most autonomous vehicle perception approaches are primarily reliant on modern deep neural networks (DNNs).   DNNs have shown breakthrough performance or object detection, tracking and prediction, scene segmentation, vehicle localization and mapping, providing accurate bounding boxes for vehicles and pedestrians, lane boundaries and signage over extensive datasets and on-road testing. Yet, these networks are not uniformly consistent in the quality of their perception outputs, and much can be gained by accumulating evidence over time.  In this talk, I will lay out our progress in 3D object detection to improve detection accuracy for a range of sensor configurations, and demonstrate the effects of adverse weather on these approaches.  Further, I will describe our approach to providing reliable uncertainty estimates for network outputs that enable proper Bayesian inference when incorporating prior information and tracking object motion through time.

APPLICATION OF COMPRESSED SENSING THEORY TO RADAR SIGNAL PROCESSING: TUTORIAL AND RECENT DEVELOPMENTS

 

Date:  Thursday July 11th, 2019.

Time:  10:30 – 11:30 AM

Location: Royal Military College of Canada, Kingston, Room S4214

Speaker:  Dr. Soheil Salari

 

Abstract

During the last decade, the emerging technique of compressed sensing has become a popular subject in signal processing and sensor systems since it can reduce the sampling rate and computational complexity of practical systems without performance loss. The technique of compressed sensing has been successfully applied in signal acquisition, image compression, and data reduction. Based on compressed sensing theory, the original radar echo can be sampled at a lower rate, and then the detection and imaging can be implemented. Although the theory of compressed sensing has been investigated for some radar and localization problems, several important questions have not been answered yet. This presentation introduces the main principle of compressed sensing theory, and then reviews some recent developments in the application of the compressed sensing theory to radar signal processing.

SECURITY IN SDN/NFV AND 5G NETWORKS – OPPORTUNITIES AND CHALLENGES

&

MOBILITY HANDOVER OPTIMIZATION FRAMEWORK AND IEEE 5G INITIATIVE

 

 

Date:  Tuesday April. 2nd, 2019.

Time:  10:30 AM

Location: Queens University, Walter Light Hall, Room 302

Speaker:  Dr. Ashutosh Dutta

 

Talk 1: Security in SDN/NFV and 5G Networks-Opportunities and Challenges – 30 minutes

Software Defined Networking (SDN) and Network Function Virtualization (NFV) are the key pillars of future networks, including 5G and Beyond that promise to support emerging applications such as enhanced mobile broadband, ultra low latency, massive sensing type applications while providing the resiliency in the network. Service providers and other verticals (e.g., Connected Cars, IOT, eHealth) can leverage SDN/NFV to provide flexible and cost-effective service without compromising the end user quality of service (QoS). While NFV and SDN open up the door for flexible networks and rapid service creation, these offer both security opportunities while also introducing additional challenges and complexities, in some cases. With the rapid proliferation of 4G and 5G networks, operators have now started the trial deployment of network function virtualization, especially with the introduction of various virtualized network elements in the access and core networks. These include elements such as virtualized Evolved Packet Core (vEPC), virtualized IP Multimedia Services (vIMS), Virtualized Residential Gateway, and Virtualized Next Generation Firewalls. However, very little attention has been given to the security aspects of virtualization. While several standardization bodies (e.g., ETSI, 3GPP, NGMN, ATIS, TIA) have started looking into the many security issues introduced by SDN/NFV, additional work is needed with larger security community involvement including vendors, operators, universities, and regulators. This tutorial will address evolution of cellular technologies towards 5G but will largely focus on various security challenges and opportunities introduced by SDN/NFV and 5G networks such as Hypervisor, Virtual Network Functions (VNFs), SDN Controller, Orchestrator, Network slicing, Cloud RAN, and security function virtualization. This tutorial will also highlight some of the ongoing activities within various standards communities and will illustrate a few deployment use case scenarios for security including threat taxonomy for both operator and enterprise networks. In addition, I will also describe some of the ongoing activities within IEEE Future Network initiative including roadmap efforts and various ways one can get involved and contribute to this initiative.

 

Talk 2: Mobility Handover Optimization Framework and IEEE 5G Initiative – 30 minutes

As mobile networks continue to grow and converge with the Internet, new wireless devices and their use are outnumbering the use of fixed network. Mobility management needs to meet the requirements of existing and emerging network technologies and applications. It may be supported in different layers of the network protocol stack. At the IP layer, Mobile IP, an IP-based mobility management, has the advantage of being applicable in any IP-based network, but is faced with many deployment challenges. Numerous variants of Mobile IP have been proposed to address these challenges in different network environments. Research in mobility management has become more active, especially with the mobile networks continuing to evolve from hierarchical towards more flattened network and densification of wireless networks. This talk presents the basics, recent advances, and future directions for mobility protocols at various layers (e.g., network, transport and application). This talk then provides taxonomy of existing mobility protocols, illustrates an abstract mobility model that can be used to support various handoff scenarios. Various handoff optimization methodologies will be explained supported by experimental and simulation results. This talk cites a few deployment scenarios to describe applicability of mobility protocols to various network environments. Finally, the talk goes through the best practices for mobility management and provides some research directions.
