Multirotor unmanned aerial vehicles (UAVs) are mechanically simple and highly maneuverable robots that are suitable to a wide range of applications such as infrastructure inspection, transportation, search-and-rescue missions, and mapping operations. To support these applications, my research vision is to expand reliable autonomous multirotor navigation beyond lab demonstrations to real-world environments. To enable this, in the first part of this talk, we present computationally efficient control algorithms, by exploiting a property of the dynamics knowns as differential flatness.  We exploit this property to enable efficient prediction and safe learning using online data.  We develop safe high-performance control by accounting for nonlinear and unknown dynamics in a computationally tractable way. In the second part of this talk, we explore some of the challenges to high-speed autonomous vision-based flight. Real-world environments may be GPS-denied and vision-based navigation, relying predominantly on an onboard camera, is a lightweight and cost-effective alternative. Most standard controllers are perception-agnostic and tend to assume (i) the action computed by the controller has no effect on the ability of vision-based navigation to determine location and (ii) perfect state estimation is obtained. These assumptions often limit the reliability and performance of perception-agnostic controllers for autonomous vision-based flight. In the second part of this talk, we present perception-aware control algorithms that account for partial knowledge of the environment and plan despite imperfect state estimation. These approaches are validated through outdoor experiments on a DJI M600 multirotor where we demonstrate autonomous vision-based flight at speeds up to 10 m/s. Finally, I will discuss some of the open gaps to robust high-performance autonomous multirotor navigation.

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


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.


Tony Chan Carusone has been a faculty member at the University of Toronto since completing his Ph.D. there in 2002.  He has co-authored eight award-winning papers on chip-to-chip and optical communication circuits, ADCs, and clock generation.  He has also been a consultant to industry since 1997.  He is currently the Chief Technology Officer of Alphawave in Toronto, Canada.

Dr. Chan Carusone was a Distinguished Lecturer for the IEEE Solid-State Circuits Society 2015-2017 and served on the Technical Program Committee of the International Solid-State Circuits Conference from 2015-2021.  He co-authored the latest editions of the classic textbooks “Analog Integrated Circuit Design” along with D. Johns and K. Martin, and “Microelectronic Circuits” along with A. Sedra and K.C. Smith. He has served as Editor-in-Chief of the IEEE Transactions on Circuits and Systems II: Express Briefs, an Associate Editor for the IEEE Journal of Solid-State Circuits, and is now Editor-in-Chief of the IEEE Solid-State Circuits Letters.  He is a Fellow of the IEEE.

Date:  Wednesday November 20th, 2019.

Time:  12:30 – 1:30 PM

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.

He was recruited to Waterloo from Stanford in 2008, where he founded and directs the Waterloo Autonomous Vehicle Laboratory (WAVELab), extending the state of the art in autonomous drones and autonomous driving through advances in localization and mapping, object detection and tracking, integrated planning and control methods and multi-robot coordination. His work on autonomous vehicles has resulted in the Autonomoose, the first autonomous vehicle created at a Canadian University to drive on public roads. His insights into autonomous driving have been featured in the Globe and Mail, Toronto Star, National Post, the Rick Mercer Report, and on national CBC Radio.  In 2018, he joined the University of Toronto Institute for Aerospace Studies (UTIAS), and founded the Toronto Robotics and Artificial Intelligence Laboratory (TRAILab).

The Joint Communications & Computer Chapter of IEEE Kingston Section is proud to present the following IEEE Lecture:




Date:  Thursday July 11th, 2019.

Time:  10:30 – 11:30 AM

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

Speaker:  Dr. Soheil Salari



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.
