Channel modeling for Kiosk downloading communication system at 300 GHz

摘要

In the race towards ultra-high-data-rate wireless communication systems, terahertz (THz) band communication is envisioned as a key wireless technology to satisfy this demand and overcome the spectrum scarcity of current wireless systems. As more and more users prefer to accessing digital information with mobile device anytime and anywhere, the close proximity data transfer are needed. In this paper, propagation channel at 300 GHz is studied for Kiosk downloading application. Key parameters of the propagation channel are extracted and modeled based on measurements and calibrated ray tracing simulations. The developed channel model allows for fast generation of channel transfer function. Moreover, the modeling results are evaluated in terms of Rician K-factor and root mean square delay spread. The absolute mean errors of these two metrics are 0.9 dB and 0.07 nanoseconds, respectively. The validated channel model can be used for close proximity communication system design at THz frequencies.
