| Abstract : |
In this presentation, we overview the ultra-low power wireless communication design. We cover both application and technology domains, and include both theoretical analysis and practical consideration. We also provide sufficient analytical, simulation, and experimental results. This presentation is divided into three parts. First, we will define the ultra-low power wireless communications and introduce its principles. Then, we will discuss potential solutions to achieve ultra-low power wireless communications. These include baseband signal processing design, Media Access Control (MAC) protocol design, cross-layer solution, system architecture selection, analog circuit-level design. Especially we will introduce IMEC’s main achievements developed in the past 8 years. Finally, we will point out the challenges that need to be addressed in practical implementation. This part will include the effect of imperfect integrated circuits, and interferences from neighboring networks. The possible solutions include the improved modulation schemes, enhanced signal processing algorithms, and coexistence study. |

Li Huang received his B. Eng degree in Electronics and Information Engineering from Huazhong University of Science & Technology (HUST) and his Ph. D degree from both the National University of Singapore (NUS) and the Technische Universiteit Eindhoven (TU/e).
Since he joined Interuniversity Microelectronics Centre (IMEC) at Holst Centre in 2006, he has been involved in various industry and European projects on ultra low power design for different wireless communication systems. He has also been active in different wireless standards. He designed baseband algorithms for IMEC’s ultra wideband (UWB) Integrated Circuit (IC) chip, which is known to be the first digital chip for the IEEE 802.15.4a standard. He also contributed several proposals for the emerging IEEE 802.15.6 standard.
He has published more than 40 papers/reports/books, one of which was among the top 10 of most downloaded papers in IEEE Transactions on Signal Processing in 2007. In addition, he has been the session chair, technical editor, invited speaker, technical reviewer in many recognized international journals and conferences. He has also supervised Ph.D. and Master Students from several renowned universities.
His research interests include signal processing (estimation, equalization, detection, synchronization, etc.), link budge analysis, channel modeling, coexistence study, Media Access Control (MAC) protocol design, wake-up radio, system-level and cross layer design for wireless sensor networks. |
