That copper telephone wire coming into your home was never designed to stream the latest blockbuster movie to your computer. One of the reasons it can today is because of some ingenious engineering by a University of Toronto researcher who co-invented computational techniques for squeezing high-capacity bandwidth from legacy communications systems.
Communication networks are never fast or efficient enough for Dr. Wei Yu. The Canada Research Chair in Information Theory and Wireless Communications has spent his career creating practical applications that stretch the limits of wired and wireless networks so they become more cost-effective and better performing.
He developed mathematical algorithms for optimizing capacity and increasing the power efficiency of digital subscriber line (DSL) networks. The technology has been implemented in over 100 million copper telephone lines by telecom companies throughout the world.
Dr. Yu has also made important contributions to the development of next-generation wireless cellular networks, which power high-speed mobile data access for smart phones, tablets and laptops. His current research is in examining the future architecture of wireless network infrastructure and in designing novel signal processing techniques to improve the transmission speeds of wireless data access.
A prolific scholar with over 10,000 citations to his credit, Dr. Yu has received several awards, including the Early Research Award from Ontario, the Institute of Electrical and Electronics Engineers (IEEE) Signal Processing Society Best Paper Award and an NSERC Discovery Accelerator Award. He has also been recognized as Fellow of the IEEE and as a Highly Cited Researcher by Thomson Reuters.
