Channel Measurement and Analysis in an Indoor Corridor Scenario at 300 GHz

The TeraHertz (THz) band, spanning the spectrum from 0.1 THz to 10 THz, is envisioned as a key technology in the next generation mobile communication systems. However, the much higher frequencies in the THz band prevents the effective utilization of channel models dedicated for microwave or millimeter-wave frequency bands. To address this problem, numerous measurement campaigns are needed to fully investigate the characteristics of the THz channels. In this paper, a measurement campaign is conducted in an indoor corridor scenario at 306-321 GHz with a frequency-domain Vector Network Analyzer (VNA)-based sounder. The measured data are further processed to obtain the channel impulse response (CIR) and power-delay-angle profile (PDAP), based on which the multipath components (MPCs) are further extracted. Furthermore, the MPCs are clustered using the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm and the clusters are matched with propagation paths by considering the real geometry. Moreover, the channel characteristics, including the path loss, delay spread, angular spreads, and cluster parameters are calculated and analyzed. The resulting numerology is helpful to guide system design for THz communications.
