Terahertz Wireless Communications: A Key Enabling Technology for Beyond 5G

Terahertz Wireless Communications: A Key Enabling Technology for Beyond 5G


Terahertz (THz)-band (0.1-10 THz) communication is envisioned as a key wireless technology of the next decade. The THz band will help overcome the spectrum scarcity problems and capacity limitations of current wireless networks, by providing an unprecedentedly large bandwidth. In addition, THz-band communication will enable a plethora of long-awaited applications, both at the nano-scale and at the macro-scale, ranging from wireless massive-core computing architectures and instantaneous data transfer among non-invasive nano-devices, to ultra-high-definition content streaming among mobile devices and wireless high-bandwidth secure communications.

The objective of this course is to provide the audience with the necessary knowledge and tools to contribute to the development of wireless communication networks in the THz band. For this, the state-of-the-art technologies, the open challenges, and possible research directions in the following three aspects will be covered. First, THz-band devices will be surveyed, including THz-band transceivers, broadband antennas and dynamic antenna arrays. Second, existing THz-band channel models, including line-of-sight channel, multi-path channel and three-dimensional channel, will be described. The open research challenges of the Ultra-Massive Multiple-Input Multiple-Output (UM-MIMO) channel and the time-varying channel will be introduced. Third, novel communication mechanisms such as the pulse-based modulation, multi-wideband modulation, distance-aware resource allocation, low-sampling-rate timing acquisition, and UM-MIMO adaptive systems will be presented.
