Millimeter-Wave and Sub-THz Channel Measurements and Characterization Analysis in a Street Canyon Scenario

Wireless communication systems that operate at frequencies higher than 100 GHz are becoming increasingly important in the future due to the availability of wide unused bandwidth (BW) that supports high data rates. In this paper, propagation characteristics of the E-band and D-band are compared based on wideband channel measurements conducted in an outdoor environment for both line-of-sight (LoS) and non-LoS (NLoS) scenarios. The channel statistics including the power delay profile (PDP), path loss (PL), Root Mean Square (RMS) Delay Spread (DS), and Ricean K factor (KF) are presented and analyzed. In addition, the path loss exponents in both frequency bands estimated using the close-in (CI) and floating-intercept (FI) models are presented.
