Second International Workshop on Wireless Communications in Terahertz (IWCT)

Monday, 3 June 2024, 9:00-12:30, Room Toucan
Organisers:
  • Kenta Umebayashis (Tokyo Univ. of Agriculture and Technology, JP)
  • Nuutti Tervo (Univ. of Oulu, Centre for Wireless Communications – Radio Technologies (CWC-RT)/ 6G Flagship, FI)
  • Joonas Kokkoniemi (Univ. of Oulu, Centre for Wireless Communications – Radio Technologies (CWC-RT)/ 6G Flagship, FI)

Motivation and Background

The goal of this workshop is to enhance synergies and cooperation among experts from different research fields, such as RF circuit design, hardware and channel modelling, communications engineering, and digital signal processing for Terahertz wireless communications. The 6G dreams for extreme data-rate targets approaching hundreds of Gbits/s, or even Tbit/s require large signal bandwidths bandwidth. The suitable spectrum for these scenarios is looked at from higher frequencies at Terahertz and sub-terahertz (0.1 – 10THz) frequency bands. Recently, visions for building cellular-like wireless communications in these bands have been criticized due to many reasons ranging from the practical business cases and deployment scenarios up to the challenges related to cost- and energy feasible transceiver hardware. Experts are actively solving these challenges in different research areas. What are the use cases for THz communications? What are suitable technologies and transceiver architectures? How to realize feasible power consumption and cost? What are the challenges and opportunities in communication signal processing? How to tackle the increased impact of RF impairments? How the essential signal processing techniques such as equalization and synchronization can be realized? What does a sub-THz radio channel look like? Which are the most promising waveform candidates? In this workshop, the experts from different fields will introduce their works and development in the THz and Sub THz area and discuss openly and interactively to enhance synergies to solve and identify the most critical THz communication challenges. Cooperation among different fields has the potential to solve the difficult challenges and relax the requirements with innovative co-design to find the winning receipt for successful wireless communications at THz and sub-THz frequencies. In this workshop, not only the members from EU projects, such as but also the other non-EU members are involved in enhancing international activities and collaboration for enabling THz wireless communications in future systems.
