Terahertz (THz) communications have naturally promising physical layer security (PLS) performance since narrow beams created by antenna arrays can effectively prevent eavesdroppers outside the beam from overhearing legitimate messages. However, eaves

Modulations for Terahertz Band Communications: Joint Analysis of Phase Noise Impact and PAPR Effects
Publikováno v:
IEEE Open Journal of the Communications Society, Vol 5, Pp 412-429 (2024)
The choice of modulation techniques for next-generation communications in the sub-terahertz and terahertz bands remains largely unresolved. A variety of traditional and new schemes show promise, but the question remains open on the illustrative compa
