Speech Title: Pervasive Channel Modeling for 6G/B6G Radio and Optical Wireless Communication Networks

Abstract: Channel characterization and modeling are the foundations of system design, performance evaluation, network planning/optimization, and standardization of wireless communication systems. Future sixth generation (6G) and beyond 6G (B6G) wireless communication systems are envisioned to provide global coverage, all spectra, full applications, and strong security. Therefore, 6G standard channel models should support global coverage, all spectra, and all application scenarios. This keynote will first discuss a novel 3D channel model for indoor visible light communication (VLC) systems, with a comparison of channel characteristics between optical wireless and radio channels. Then, a 6G pervasive channel model (6GPCM) is proposed to integrate channel statistical properties of all frequency bands and all scenarios. Finally, 6G channel simulation platforms and applications are briefly illustrated, such as digital-twin online channel modeling, indoor positioning, network planning, and network optimization.

Speech Title: Superconducting Adiabatic Logic for Beyond-CMOS Computing: Principles and Prospects

Abstract: The recent rapid growth of high-performance computing applications, such as artificial intelligence and cryptocurrency, has significantly increased the demand for more energy-efficient computing technologies. However, CMOS technology is approaching its physical and practical limits, as predicted by the end of Moore’s Law, and is hard to keep up with this growing demand. Superconducting computing has emerged as a promising post-CMOS alternative, offering significant advantages in both speed and energy efficiency. Among the various superconducting logic families, superconducting adiabatic logic circuits are particularly notable for their extremely low energy consumption. They can operate with switching energies even below the thermal energy limit (kBT ln2), known as Landauer’s limit. This cutting-edge technology holds great potential for a wide range of applications where energy efficiency is critical, including classical high-performance computing as well as control and readout circuitry for quantum bits. In this presentation, I will provide an overview of our recent research on superconducting adiabatic logic circuits and discuss the future prospects and challenges of this emerging technology.

Speech Title: Multiplexing Technologies for Next-Generation Datacenter Networks
Abstract: It is forecasted that the operating speed of the single-lane ethernet will be increased to 400 Gb/s by mid-2030s [1].  Thus, for the datacenter applications, in which cost-effectiveness is critical, it would be necessary to develop the intensity-modulation/direct-detection (IM/DD) systems operating at such a high speed in the near future.  However, considering the current trends in the development of the high-speed optical modulators, it appears to be tremendously challenging to achieve this objective in time.  To overcome this problem, we believe that it is inevitable to utilize some sort of the multiplexing technology.  Accordingly, at KAIST, we evaluate the feasibility of drastically increasing the per-lane transmission speed of the short- reach IM/DD system by utilizing various multiplexing technologies such as the orthogonal- frequency-division-multiplexing (OFDM), optical-time-division-multiplexing (OTDM), mode- group-division-multiplexing (MGDM), and polarization-division-multiplexing (PDM) [2]-[6].  Some of these results will be presented at the conference together with their implications and outlooks for the future.
