Abstract
Modulation is essential to convey information through a communication
system. This chapter gives an overview of the modulation schemes and their
use to date in THz systems. The choice of a modulation scheme is a trade-off of
factors such as noise, the RF channel, cost/complexity and component technologies.
THz systems fall at a technology cusp between optical and RF systems. Spectral
efficiency is important at lower frequencies where the spectrum is congested but
THz frequency bands are currently underused and technical challenges like power,
high channel-losses and oscillator-phase stability dominate the design choices.
