Sub-THz Outdoor Urban Measurements and Multipath Propagation Characteristics
This paper investigates sub-THz measurement-based multipath propagation characteristics. The measurements were collected in an outdoor urban environment at frequency of 159 GHz considering both LoS and NLoS link scenarios. With a rotationally-scanning directional antenna setup and a wideband sounder (5-GHz bandwidth), both spatial and temporal multipath power distributions were investigated. By comparing the multipath dispersion characteristics to the associated frequency-extrapolated 3GPP model parameters, which is valid only up to 100 GHz, we found that the delay spread and the angular spread statistics in the 3GPP model deviated from our 159-GHz measurement data.
