Over the last decades, we have gradually seen digital circuits take over applications that were traditionally bastions of analog circuits. One of the reasons behind this tendency is our ability to detect and correct errors in digital circuits. This ability led to faster and more reliable communication and storage systems. Nowadays, each home easily contains tens of decoders for error-correction codes. While we know about channel capacity since the very late 1940s, i.e., how good an error-correction solution can be, the theoretical work of Claude Shannon does not tell us how this limit can be reached. From the algebraic codes of the 1950s to the current modern codes that make the solution adopted in the latest 5G standard, we know how to get extremely close to channel capacity, and in some cases, we even know how to reach it. Yet, we still do not achieve channel capacity in practical systems. Why is that? There is more to an error-correction solution than error-correction performance. What are the metrics that matter? Are we optimizing for throughput, latency, area, energy efficiency, or something else? As with everything in engineering, IT DEPENDS, and our work is almost always about finding the best trade off. Various applications call for different priorities. Complicating the issue even further, those priorities often conflict with each other. In this talk, I will go over a few of the challenges and opportunities that come with the design and implementation of error-correction solutions. Supported with examples and results, I will also show how important it has become to simultaneously innovate at various abstraction levels.
Note biographique: Pascal Giard (IEEE Senior Member) received the B.Eng. and M.Eng. degrees in electrical engineering from the École de technologie supérieure (ÉTS), Montréal, Canada, in 2006 and 2009, respectively, and the Ph.D. degree from McGill University, Montréal, Canada, in 2016. From 2009 to 2010, he worked as a research professional in the NSERC - Ultra Electronics Chair in Wireless Emergency and Tactical Communications at ÉTS. From 2007 to 2016, he was a Lecturer in the Department of Electrical Engineering, ÉTS. He also collaborated as a research professional in the Research Chair in Design Methodology for Highly Integrated and Reliable Hybrid Systems at ÉTS from 2012 to 2016. Then, from 2016 to 2018, he worked with Prof. Andreas Burg as a Postdoctoral Researcher at the Telecommunication Circuits Laboratory (TCL), Ecole polytechnique fédérale de Lausanne (EPFL), Switzerland. He joined the Electrical Engineering Department of ÉTS in 2018, where is currently is an Associate Professor. His research interests are in the design and implementation of signal processing systems with a focus on embedded systems, connected objects, and modern error-correcting codes. Dr Giard received the Best Experimental-Demonstration Award at the IEEE CASS & ReSMiQ Innovation Day 2015. He is a member of ReSMiQ and OIQ, and has organized both the 2021 International Symposium on Topics in Coding (ISTC) and the 2022 ISTC Workshop. He serves as a reviewer for several IEEE journals and conferences, and served as an Associate Editor for the Elsevier MicroElectronics Journal (MEJ) from 2016 to 2020. He currently is an Associate Editor for the Coding area of IEEE Communications Letters.
