Waveform and Modulation Design of Terahertz Communications

Terahertz (THz) communication is envisioned as a key technology for 6G, which is expected to support 1 Tbps peak data rate, 0.1 millisecond latency, millimeter-precision sensing and positioning, and end-to-end reliability in terms of packet error rates of 10–9. As a fundamental wireless infrastructure, the THz communication can boost abundant promising applications, including metaverse, THz wireless backhaul, and THz space networks, as well as other long-awaited novel communication paradigms. In light of the ongoing THz hardware and channel developments, efficient waveform and modulation technologies are investigated in this chapter, to make the most use of the THz spectrum.
